Making the decision to change your smile through cosmetic dentistry can take time and a careful discussion with your dentist regarding the best options for you. Porcelain veneers are an excellent option for transforming your smile from ordinary to dazzling. When making such a big decision it should be an educated one. Porcelain veneers are a great option for those who want to change their smile shape and give you that perfect smile. Understanding what they are, what they can do for your appearance, and the procedures involved.
What Are Porcelain Veneers?
Porcelain veneers are super thin, custom fabricated shells of tooth-colored materials designed to cover the front surface of teeth to improve your smile. These porcelain shells are adhesively bonded to the front of the teeth. Porcelain veneers have the ability to change the color, shape, size, or length of your teeth.
Porcelain veneers have the following characteristics:
-Translucent qualities — Like natural tooth enamel, porcelain veneers are translucent, meaning they allow some light to pass through and reflect off the natural dental material. This gives the veneer a natural depth, providing for a dazzling smile.
-Color matching — If you are replacing multiple teeth, then all your veneers can be a natural, bright color. When covering just one or two teeth, porcelain veneers can easily be matched to the surrounding natural teeth in order to provide a consistently beautiful smile.
-Non-porous surface — Porcelain veneers are ceramic glass and are non-porous, preventing future stains from ruining your new smile.
What Can Porcelain Veneers Do For Your Smile?
Porcelain veneers are used in cosmetic dentistry to alter your front teeth in a variety of ways. These include:
-Making shorter teeth longer.
-Reshaping a smile
-Changing color (porcelain veneers can can be viewed as permanent teeth whitening)
-Restoring worn teeth with weak or worn down enamel.
-Close Gaps Between Teeth.
-Repairing cracked, chipped, or broken teeth.
-Minor Realignment Of Teeth. Porcelain veneers are also called “instant orthodontics” for this reason. They can straighten slightly out of place teeth to create a perfect smile.
Porcelain veneers are generally completed across the front 6 teeth on either the top or bottom or both. Single porcelain veneers can also be done to change individual teeth with minor flaws.
Additional Benefits Of Porcelain Veneers
Porcelain veneers can also change other parts of your face. This can include:
-Lip Enhancement – The extra layer that porcelain veneers add to teeth pushes the lips just slightly outward, can lead to fuller lips that look very natural.
-Strengthening sensitive teeth – Worn teeth lacking enamel will make patients feel twinges when their teeth are exposed to hot or cold. Porcelain veneers will strengthen the teeth by covering the exposed layers of the tooth leading to improved comfort.
Procedures involved in Porcelain veneer fabrication
-Most teeth require some removal of enamel to shape and prepare the surface for the veneer.
-Impressions of the teeth before and after the preparations.
-Diagnostic study models and photos are to find what will look best.
-Temporaries are worn while the veneers are being created.
-Veneers are adhered to the teeth with bonding resins.
-Proper maintenance and care at home and with regular professional cleanings.
The decision to have porcelain veneers is a large and permanent commitment. You need to understand and decide whether this procedure is right for you. If you find that porcelain veneers are the correct choice, you and your dentist can work up and design your custom smile. Following placement of your new porcelain veneers you are able to leave the dentist office with the smile of your dreams. Once your permanent veneers have been placed and bonded to your teeth, you can enjoy the many benefits that they have to offer immediately. Your cosmetic dentist will give you proper aftercare instructions so you can maintain your new smile for years to come. It is important to maintain regular dental examinations and professional cleanings to keep your smile looking its best for years to come.
Dental veneers are wafer thin, custom fabricated shells of tooth colored materials designed to cover the front surface of teeth to improve your overall smile and appearance. These custom fabricated shells are adhesively bonded to the front of the teeth. This allows the cosmetic dentist the ability to change your teeth’s color, shape, size, or length.
Dental veneers can be fabricated from dental porcelain or from composite (resin) materials. Dental veneers can be used to create bright, white smiles with beautifully aligned, shapely teeth. Dental veneers also protect the surface of broken or damaged teeth, and may eliminate the need for more extensive treatments. Other advantages of dental veneers include durability, an improved smile, and the need for much less tooth structure removal compared to traditional or porcelain crowns.
Why are Dental Veneers Needed?
Dental Veneers are utilized for a variety of reasons in cosmetic dentistry. These reasons can include:
–Crooked Teeth. Some minor modifications can be done, which may eliminate the need for orthodontic movement.
–Genetics. Certain people are born with abnormal sized/shaped teeth, or gaps between their teeth that widen with age.
–Wear and Tear. Teeth wearing down is a natural part of aging. Aged teeth are more likely to be small, have chips, fractures, cracks or a generally uneven appearance.
–Worn Enamel. Over time, the thin, hard translucent substance covering your teeth (enamel) may become worn, see through, dull, or discolored. Such wear and discoloration may be natural or result from a genetic predisposition. However, it often results from consuming soft drinks, tea or coffee, smoking, using certain medications, etc.
Material Used for Dental Veneers
The most commonly utilized materials for dental veneers are composite resins and dental porcelain. Porcelain veneers are the more appropriate answer for severe cases involving dullness, wear, tooth discoloration, extensive chipping, cracking, gaps in teeth or uneven teeth. Composite bonding or just dental bonding is an inexpensive, effective and minimally invasive way to restore and correct small chips, cracks and discoloration in the teeth. Porcelain veneers generally require some reduction of the enamel tooth surface, while bonded dental veneers can oftentimes be done without tooth modification. Porcelain veneers are very strong, and do not change color. Bonded veneers tend to chip and pick up stain over time.
Techniques Used in Dental Veneers
Indirect Technique – This technique means that the composite or porcelain veneers are fabricated outside the mouth by a dental technician in a laboratory.
Direct Technique – This technique means that the composite veneers are created directly on your teeth by your dentist during your appointment.
When are Veneers Good Treatment?
The removal by a dentist of any natural tooth structure is permanent, so modern cosmetic dentistry has moved to offer patients the most minimally invasive options first. If your natural teeth are functionally and cosmetically adequate, dental veneers may not be the right treatment for you.
On the other hand, if you have any of the aforementioned cosmetic issues, your treatment options may include veneers. Dental Veneers do have the advantage of a proven ability to enhance the appearance of the mouth, smile and other facial features that are better supported by properly shaped teeth.
If modification of the tooth surface is necessary to achieve optimum results, some cosmetic dentists will recommend less invasive alternatives to dental veneers. One such alternative would be, teeth whitening for people with mildly discolored teeth who only want a whiter and brighter smile. If crooked teeth or alignment issues are involved, the teeth whitening alternative may also be combined with orthodontic treatments. Invisalign, full braces, or use of an orthodontic appliance for minor tooth movement may be all that you need to acquire the smile you desire.
Care of Dental Veneers
Care must be taken not to abuse dental veneers because the wafer thin porcelain shells or composite layers can be damaged or break. Your dentist may advise you against grinding, fingernail chewing, and biting directly into things such as carrots or pizza crusts. If you grind at night your dentist may recommend you wear a night guard while sleeping. It is even more important to have excellent dental hygiene, so that you do not get tooth decay forming under your dental veneer. You should also see your dentist for regular cleanings.
Dental Veneers Conclusion
Dental veneers, whether porcelain veneers or composite veneers, are a great option for those who wish to change their smile. Dental veneers give the cosmetic dentist and patient the ability to change color, shape, and size in an easy manner. As always, before pursuing dental veneers of any kind, please have a thorough dental examination and professional cleaning performed to ensure your mouth is healthy and able to withstand the new treatment.
Have you ever caught yourself staring at the perfect smiles seen on TV, in the movies, and in magazines . . . the smiles of Hollywood actors and actresses, and models? Have you ever wondered, “How did they get that perfect, white smile? Odds are, those celebrities were not born with pearly white smiles. These smiles were likely designed and created just for them with the help of a cosmetic dentist. The good news? Anyone can enjoy the perfect Hollywood smile, with the assistance of a cosmetic dentist and porcelain veneers.
Porcelain veneers (also referred to as porcelain laminates) are super thin, custom fabricated shells of tooth colored porcelain designed to cover the front surface of teeth to improve your smile’s overall aesthetic appearance. These shells are adhesively bonded to the front of the teeth changing their color, shape, width, and/or length. Versatile and very strong, porcelain veneers are used in a variety of ways to transform your smile, from complete smile makeovers to repairing a chipped tooth.
Porcelain veneers are custom made from a high quality dental porcelain that has similar light reflecting properties as our natural teeth. Porcelain veneers are excellent at resisting stains and they mimic our natural teeth’s light reflecting properties. They are the cosmetic dentist’s greatest tool for elevating a normal smile to a Hollywood smile.
-Teeth that are stained or discolored. Teeth can become stained or discolored from root canal treatment, from tetracycline or other drugs, excessive fluoride, or the presence of large resin fillings that have discolored over time.
-Teeth that are worn down from use or grinding of teeth.
-Teeth that are broken or chipped.
-Teeth that are misaligned, uneven, or irregularly shaped. Porcelain veneers are sometimes referred to as “Instant Orthodontics”.
-Teeth with gaps or spaces between them. Porcelain Veneers are able to cosmetically close those spaces.
Making the decision to have porcelain veneers is the first step. The entire process usually takes 3-4 visits, one for a consultation and two to make and apply the porcelain veneers. There is sometimes an added appointment following the consultation where the dentist will show the patient a mock up model. This model will be of your teeth where the dentist has waxed onto those teeth what the porcelain veneers will look like on your smile. It is a great visual reference for you to decide the course of treatment for you. This can also be done via software on a computer. One tooth or many teeth can simultaneously undergo the treatment described in the following paragraphs.
Consultation/Diagnosis and Treatment Planning. This first step involves your active input. Explain to your dentist what you want in the final result. During this appointment, your cosmetic dentist will examine your teeth to make sure porcelain veneers are appropriate for you and explain to you what the procedure involves and some of its drawbacks. They may take X-rays and possibly make impressions of your teeth as study models. These models will be used by the dentist to do a mock up of the final result. The dentist will prepare the teeth on the model and sculpt wax over them to give you a visual representation of the final product. This is an important step.
Preparing the Teeth for Porcelain Veneers. A dentist must remove about 1/2 millimeter of enamel from the tooth surface, which is an amount nearly equal to the thickness of the porcelain veneers to be added back to the tooth. Before beginning, you and your dentist will decide the need for a local anesthetic to numb the area. Next, your dentist will take an impression of your teeth. This model is sent out to a dental laboratory, which in turn constructs your custom porcelain veneer. It takes about 1-2 weeks for the laboratory technicians to complete the process. Temporary veneers are placed using a resin material until the final veneers are ready.
Dental Bonding. Before the porcelain veneers are permanently bonded to your tooth, the dentist will check for fit and color by temporarily placing it on the tooth. If they fit properly and the color shade is correct the dentist will go on to prepare your tooth, your tooth will be cleaned, polished, and etched (this is a process whereby your tooth surface is roughened up chemically at the microscopic level). A special adhesive is applied to the porcelain veneers and the veneer or veneers are methodically placed on your tooth. When the they are in the right position, your dentist will apply a special light to the porcelain veneers. This activates chemicals in the adhesive, causing it to cure. The final steps involve removing any excess adhesive, evaluating your bite and making any final adjustments in the porcelain veneers as needed. Your dentist may ask you to return for a follow-up visit in a couple of weeks. This is to ensure you are happy with the final result as well as checking the gum tissue surrounding the new porcelain veneers.
There are some disadvantages to porcelain veneers:
-The procedure is not reversible.
-Porcelain Veneers are not repairable. If they break, a new one will need to be custom fabricated in the laboratory.
-The color cannot be changed once the porcelain veneers are in place. So both dentist and patient must be sure they are happy with color prior to final placement of the porcelain veneers. It does happen on occasion that the color is not what is desired from the laboratory and they are sent back to be remade. It is of the utmost importance for the patient to be ahppy and satisfied with the final result.
-Porcelain veneers can fall off or chip. The material is very strong but patients who grind their teeth, bite their nails or chew on pencils will be more susceptible to this occurring.
-The teeth under the porcelain veneers are still susceptible to tooth decay. Patients need to be made aware of maintaining proper oral hygiene.
Porcelain veneers can be brushed, and flossed just like your own teeth. You should not even know they are in your mouth as they are bonded to your natural tooth sstructure.
Imagine. In just a few short visits, you can have an amazing Hollywood smile . . . a smile that has been custom designed just for you. A smile that is straighter and whiter than you could have imagined. You’ll be looking younger and feeling more confident. And it’s all possible with your cosmetic dentist and porcelain veneers.
porcelain crowns would be as durable over the long term. Well, recent clinical studies have shown that they are just as strong and also have the ability to maintain their beauty over time as well.
The main differences in porcelain crowns are the type of porcelain used, and how they are fabricated in a dental laboratory. Different porcelain types and strengths are used for different reasons. Remember also, that a lab created porcelain crown, is of higher fabrication quality and fit, than an in office computer milled crown.
Long Term Study – Porcelain Crowns
The researchers at the Medical University at Innsbruck studied a little over 1,300 all porcelain crowns placed between 1987 and 2009. They were tested for predictability and strength and found to have a high,(93.5% probability of survival) success over a 10 year period. The study was published in the International Journal of Prosthodontics). The study included those with root canal teeth, and those who grind their teeth.
A total of 302 patients (120 men and 182 women) participated in the study. They were examined at the university during regularly scheduled visits for dental examination. Patient-specific data about sex, age, tooth sensitivity, smoking, and grinding were noted, as well as self-reported data regarding their level of
satisfaction with their restorations: excellent, good, medium, or none. The porcelain crowns were broken down into areas of mouth as well, into front( anterior), and back( premolar, and molar) regions.
All 1,335 porcelain crowns had been placed at the university between November 1987 and December 2009. Of these porcelain crowns, 451 were observed over a 10-year period, 84 for 15 years, and 24 over 20 years.
Dental examinations were completed by two dentists in the spring of 2010. One dentist had placed the majority of porcelain crowns, whereas the other dentist involved in examinations had placed none of them. California Dental Association/Ryge criteria were used to rate each porcelain crowns as a success, relative failure, or absolute failure.
Any porcelain crowns that had severe enough issues to warrant replacement were considered an absolute failure. If a finishing procedure or polishing was able to fix the issue, the porcelain crown was labeled a relative failure.
Of the 1,300+ porcelain crowns in the study, only 95 porcelain crowns were rated as failures, 79% of which were absolute failure. Most failures occurred in the anterior region, with 65, while 19 occurred in premolars and 11 occurred in molars.
Success rates remained strong over time. The estimated survival rate was 97.3% at five years, 96% at eight years, 94% at 10 years, 85.8% at 15 years, and 78.5% after 20
years. Almost half of all porcelain crown failures happened in the first 8 years..
The most frequent reason for failure was fracture,(cracks) of the ceramic, according to the researchers, followed in order by cracks in the ceramic and decay.
Root canal teeth and patients who grind their teeth, had higher failure rates.
Patient responses to questions about satisfaction were very positive. With 96% rating it as excellent and 4% rating it as good. The surprising thing about this study was that even patients with failures thought that porcelain crowns were an ideal dental restoration and would do it all over again.
Porcelain Crowns Conclusion
Porcelain crowns are a proven part of cosmetic dentistry and with continued advances in dental porcelain (like e.max porcelain crowns) these results will be even better into the future. Porcelain crowns are an ideal restoration due to their color, shape, and light reflecting properties. The study just proves that they are a valuable asset to any dental patient’s smile.
