Brighten Your Teeth Just In One Hour !

Years of bad habits (cigarette smoking, tobacco use) and indulgence in certain beverages (soda, juice, coffee, tea) can create discolorations or stain a person’s teeth. In addition, some medications, past dental work, heredity and simply growing older can leave those once pearly whites not quite so appealing.

Now you can erase years of stains and discolorations from your teeth in about one hour with the Zoom!® tooth whitening system. The Zoom! procedure is performed by a trained cosmetic dentist in the dentist’s office.

The Process:

• The cosmetic dentist will begin the process by professionally cleaning the teeth to remove any plaque buildup.
• The dentist will then prepare the teeth to safely receive the treatment by applying a protective cover on the gums and lips.
• A hydrogen peroxide-based whitening gel is applied to the teeth and a special laser light is shined on the teeth for 15-20 minutes.
• The gel is removed and then reapplied with the light treatment two more times.
• The hydrogen peroxide acts as a bleaching agent to whiten the tooth enamel (outer tooth layer) and dentin (tooth layer surrounding the pulp).

The Results:
After the three Zoom! treatments, patients will see immediate results with the teeth appearing up to eight shades lighter than before the treatment. The results are long-lasting and can be touched-up using a take-home whitening gel kits. Patients should continue practicing good oral hygiene by brushing and flossing twice daily.

The Risks:
Dentist-supervised tooth whitening is a generally safe procedure. However, every patient will have varying degrees of tooth sensitivity that could be affected by the Zoom! tooth whitening procedure. Some patients have experienced sharp, shooting tooth pains during and sometimes after the treatments. Any patient who experiences pain during treatment should immediately alert the dentist so a de-sensitizing gel can be applied.

The Cost:
The cost of the Zoom! tooth whitening system will vary, but the treatments can range between $500-$1,500.

In-office tooth whitening treatments such as Zoom! are a quick, easy and highly effective way to brighten your entire face and give you more self-confidence.

Latest technology For Regeneration of Broken Tooth

Researchers from the University of Alberta believe they have found a method of regrowing teeth and possibly bone that have been broken. The scientists use a miniaturized low-intensity pulsed ultrasound (LIPUS) system-on-a-chip which offers a non-invasive and novel way to stimulate jaw growth and dental tissue healing.

Dr. Tarak El-Bialy from the Faculty of Medicine and Dentistry and Dr. Jie Chen and Dr. Ying Tsui from the Faculty of Engineering developed a tiny wireless ultrasound transducer device that comfortably fits inside the patient’s mouth while packed in biocompatible materials. The device is mounted on an orthodontic or “braces” bracket or even a plastic removable crown. The team also designed an energy sensor that will ensure the LIPUS power is reaching the target area of the teeth roots within the bone.

Dr. Chen says “It’s very exciting because we have shown the results and actually have something you can touch and feel that will impact the health of people in Canada and throughout the world.” Chen works out of the Department of Electrical and Computer Engineering and the National Institute for Nanotechnology.

The technology has already been patented, and they hope they will have the system-on-a-chip finished to complete the miniaturized device by next year. El-Bialy says “If the root is broken, it can now be fixed. And because we can regrow the teeth root, a patient could have his own tooth rather than foreign objects in his mouth.”

The device is aimed at people experiencing dental root resorption, a common effect of mechanical or chemical injury to dental tissue caused by diseases and endocrine disturbances. The market potential in the US alone is 1.4 million.

The device was first tested on rabbits. After positive results the scientists moved onto humans and found similar results. They have also shown that LIPUS can improve jaw growth in cases with hemifacial microsomia, a congenital syndrome where one side of the child’s jaw or face is underdeveloped compared to the other “normal” side.

Usually these patients undergo many surgeries to improve their facial appearance. The work on human patients was presented at the World Federation of Orthodontics in Paris, September 2005.

Teeth Bonding & Dental Fillings

Teeth bonding can correct minor dental flaws in one quick and easy procedure. It is sometimes used instead of porcelain veneers. Today’s bonding is tooth colored and produces beautiful results. It can be used to fill small holes, seal and protect your teeth, and to correct cosmetic flaws.

What is bonding?
Bonding refers to the substance used and to the procedure itself. Bonding material is a tooth colored paste. Your cosmetic dentist applies the bonding and shapes it while it is still soft. It can be sculpted and more can be added until just the right shape is achieved. Then it is hardened with a special light.

What is bonding used for?
Bonding can be used to create small, tooth-colored fillings for cavities.

Cracks and tooth erosion can be covered and sealed. Cracks and erosion can cause pain and sensitivity, tooth decay, and discoloration. Bonding restores the beauty and comfort of your smile, while protecting your teeth from further damage.

Bonding can be used to cover correct the look of small chips. Small gaps between your teeth can be filled by building up the surrounding teeth to close the gap.

The look of crooked and misshapen teeth can be corrected with bonding, by sculpting a new shape onto your teeth. Discoloration that is resistant to whitening can be covered.

Dental bonding vs. porcelain veneers
Dental bonding and porcelain veneers can be used to correct many of the same problems. There are advantages and disadvantages to choosing bonding over veneers.

The advantages of bonding include:
Bonding gives you faster results than veneers; bonding only requires one visit, veneers require two.
Bonding is less expensive than veneers.
Sometimes, bonding can be used to build up a larger portion of your tooth than veneers.

There are also some disadvantages to bonding:
Your bonding will match the color of your natural teeth and restore the beauty of your teeth, but it is not quite as beautiful and natural looking as veneers.
Bonding is not as stain resistant as veneers, so you have to be more careful about what you eat and drink to minimize discoloration over time, just like you do with your natural tooth enamel.
At home you will care for your teeth just like you always have with bonding, but when you have your teeth professionally cleaned you will need to see a hygienist who has experience with bonding or your bonding could be damaged.

Fillings:
Dental bonding can be used to create fillings for small holes in your teeth in one quick office visit. For larger areas of decay, your cosmetic dentist may recommend porcelain inlays or onlays. Inlays and onlays are created in a lab, so they require two office visits. The results, however are beautiful, blend seamlessly with your tooth, and strengthen your tooth.

Relation Between Porcelain Veneers & Tooth Cavity

Providing an instant smile restoration, porcelain veneers are the shining star in the cosmetic dentistry universe. However, just because there is a ceramic sheet protecting your teeth and hiding their imperfections does not mean that your teeth are now immune from future decay.

Benefits of Veneers:

• Porcelain veneers can address numerous cosmetic issues in your smile, such as:
• Discolored enamel
• Cracked, chipped, crooked or fractured teeth
• Gaps between teeth

While these are all important cosmetic benefits, porcelain veneers also act as a barrier between tooth enamel and staining agents such as sugary foods, chocolate, tobacco products, or dark beverages such as coffee, tea, or wine. However, even though the ceramic material that porcelain veneers are made of is resistant to decay, the teeth behind are still vulnerable.

Dangers To Consider:
Porcelain veneers are placed onto a person’s teeth after a small amount of tooth enamel is shaved off. However, if an inexperienced or unskilled dentist attaches the porcelain veneers, it’s possible that a ledge may exist along the border of the veneer. Over time, undetectable crumbs of food can gather in these pockets and gnaw away at your teeth, making a root canal or dental crown inevitable.

Just because there’s a shell protecting your teeth does not mean their immune from cavities. Maintaining quality oral health through daily brushing, flossing and regular dental visits is still required to guarantee the health of your teeth.

What Happens If You Get A Cavity?
It’s not the end of the world. Cavities can only occur on the area where the porcelain veneer does not cover your tooth and, so long as it’s caught early, the cavity is easy to fix.

In fact, fixing a cavity on a porcelain veneer protected tooth is the same process as fixing it on a non-veneered tooth. The only difference is if the cavity directly borders the porcelain. This then requires a procedure that will bond the composite resin material to the porcelain veneer.

Maximizing Your Porcelain Veneers Lifespan:
While maintaining good oral hygiene is important to avoiding cavities around your porcelain veneers, there are additional steps you can take to maximize your porcelain veneers lifespan.

Avoid clenching and grinding your teeth. If you grind your teeth while asleep, be sure to speak with your dentist to receive a protective mouth guard don’t chew on inedible items.

Dental Implants: Teeth Loss Treatment

Unlike sharks, humans do not have a near-infinite supply of teeth constantly growing in. Nor do we have constantly-growing incisors like rodents. Instead, we are issued a finite supply of teeth, and when they're gone, that's it. Once one tooth is gone, others can drift, crowd, and come out of alignment. The jawbone can decay, making it fragile and susceptible to breakage. It can look very unattractive, and the functions of the mouth, including chewing and speaking, can be affected.

Fortunately, cosmetic dentists have a number of solutions that are both aesthetic and functional to remedy the loss of teeth.

The Old War Horse:
With the exception of cosmetic bridges wired into the mouths of corpses following death, dentures were the first treatment for lost teeth. Dentures are prostheses that fit in the mouth, with one or more ponitcs (false teeth) that fill the spaces left by lost teeth. Dentures can be full or partial, and either top or bottom. Dentures can be a reasonable cosmetic and functional appliance, if well-made, but they can also be a poor solution for the problem of missing teeth, as they sometimes fit uncomfortably and are not fastened to the jaw, so they can slide out of place.

Fully-Functional Appliance:
Modern dental bridges are a fully-functional, highly cosmetic solution to the problem of missing teeth. In a dental bridge, the pontic (or pontics, though bridges are rarely recommended for very many teeth) are fastened to a neighboring tooth or neighboring teeth. This can be done either by modifying the supporting teeth with a dental crown, or it can be done using dental bonding that bond the pontic directly to the other teeth.

Bridges are near-perfect prostheses from both a functional and a cosmetic standpoint. Their only problem comes if bacteria begins to collect under the pontic as a result of poor oral hygiene. Their dependence on other teeth can also be a drawback, because they either require neighboring teeth to be modified with crowns, or if directly bonded they can fail if a neighboring tooth fails.

High-Tech Solution:
A dental implant goes even further toward a high-functioning and highly attractive prosthetic. In fact, a dental implant functions like the root of the tooth, and the crown on top is a fully-functioning tooth for all intents and purposes. Once a dental implant has been integrated into the jawbone, it requires no special treatment, and in most cases it will function as well or better than your natural teeth.

If you require many or all your teeth to be replaced in either arch, you can consider a system like Nobel's All-on-4 system, in which an entire arch of teeth is anchored using four implants into the jaw.

Although there are many ways to avoid the negative effects of missing teeth, the crown jewel is the dental implant.

FAQ's & Guideliness For Dental Crowns

Dental crowns can provide you with a great option for repairing damage done to your teeth. The following questions are commonly asked to cosmetic dentists by patients at their initial dental crown consultation:

What are dental crowns?
A dental crown, also known as a dental cap, is used to cover a damaged tooth and restore the tooth's strength and durability. Dental crowns cover the entire portion of the tooth visible above the gum line. This is different from a filling which only covers a portion of the visible part of a tooth.

Why would I need a dental crown?
There are many reasons why a dentist would recommend a crown including:

• Cracked teeth
• Fractured teeth
• An anchor is needed for a dental bridge to replace a missing tooth
• To cover a tooth that has had a root canal
• Fragile teeth
• Cosmetic purposes

A crown can fix a tooth that is misshapen or discolored. If you have been unhappy about the way a tooth looks, then a crown could be the answer to your problem.

How does a dentist make a dental crown?
A dentist creates a dental crown over the course of two dental appointments. During the first appointment, he will remove most of the outside surface of the tooth which will later be replaced by the crown. This is known as shaping the tooth. Once the tooth is shaped, the dentist will take several impressions of the tooth and other areas of the mouth. These impressions are sent to a dental technician who uses them to make a perfect fitting permanent crown. At the end of your first appointment, the dentist will attach a temporary crown to your tooth. During the second appointment, the dentist will attach the permanent crown to your tooth.

Is it painful to get a dental crown?
Getting a crown is a relatively painless procedure. The dentist uses a local anesthetic to numb the areas of the mouth being treated.

What are the different types of crowns?
There are three different types of crowns. They are:

• Gold Crown
• Porcelain Crown
• Porcelain-Fused-to-Metal Crown

Which crown is right for me?
This is a question for your dentist to answer. When you schedule a consultation visit, your dentist will discuss the various costs associated with a crown, the best type of crown for you, and also financing options.

Dental Implants & Dental Dentures

How do you know what is best for you and your future? Cosmetic dentures or dental implants both solve the same problem: fixing your missing teeth. You need to look at the big picture.

Cosmetic Dentures:
Cosmetic dentures are simply replacements of missing teeth. The false teeth can replace all the upper teeth or all the lower teeth (known as full dentures), or parts where groups of teeth are missing (called partials). The prosthetic teeth can be made from plastic or even porcelain. Today’s cosmetic dentures not only function, but also look aesthetically pleasing.

Cosmetic dentures are removable, nonpermanent structures which use denture adhesive to keep them in place during the day. You remove them and clean them at night.

Dental Implants:
By contrast, dental implants are a permanent solution to the problem of missing teeth. They are attached to the jawbone by the use of implanted anchors. The anchor sits below the gum line.

Titanium posts are attached to the anchors. These posts function like the teeth roots. They sit above the gum line.

Finally, a prosthetic tooth crown is attached on top of the post.

Because the implant is made of titanium, it integrates with the jawbone (called osseointegration), forming a functional and structural bond that can withstand the high-stress force that chewing creates.

Advantages of Dental Implants over Cosmetic Dentures:
When comparing cosmetic dentures and dental implants, dental implants are the preferred solution because they have several advantages:

• Aesthetics – dental implants are the closest thing to your natural teeth because they are anchored in your mouth in a duplication of the way your natural teeth are anchored in, so they look, act, and feel like the real thing.
• Confidence – dental implants look and feel like your natural teeth so they make you feel confident because you feel natural. They also don’t impede speech because they fit in your mouth the same as your natural teeth do.
• Facial stability – because dental implants provide the same support for your face as natural teeth, they can reduce or eliminate wrinkles that you may have gotten when teeth were missing. Also, they stabilize the face by holding it up so it doesn’t appear sunken. It’s almost like a face lift because sunken faces make people look much older then they actually are.
• Functionality – dental implants improve your ability to chew food because they can withstand almost as much biting and chewing force as natural teeth
• No teeth are sacrificed – dentures may require some teeth to be pulled, and partial dentures may use neighboring teeth as anchors, thus necessitating that some of those teeth be altered to support the partial denture
• Reliability - since dental implants look and function just like natural teeth, they offer you the ability to relax and feel more confident without worrying whether they will fall out. You just care for them like your natural teeth. You don’t need special cleaners or adhesives.

When looking into dental implants or cosmetic dentures, look for a cosmetic dentist that offers both accuracy and precision in both the diagnosis of missing teeth as well as the treatment solution. The combination of these tools allows him to completely envision the placement of your implants in a realistic, three-dimensional setting and create a surgical map which guides him in placing the dental implants.

Cosmetic dentures can look very good when they are designed correctly. However, when looking at the big picture, you can see that dental implants are the preferred treatment because of their advantages over cosmetic dentures.
