Not All Dental Crowns Are Created The Same!

Dental crowns are a type of dental restoration which completely covers and protects a tooth or a dental implant. Dental crowns are often necessary when a large cavity has destroyed  a good portion of the tooth, leaving it easily fracturable. Dental crowns will restore its shape, strength, and improve its cosmetic appearance. Dental crowns are typically bonded to the tooth using a specialized dental cement (in dental implants they are sometimes screwed in place). Crowns can be made from many different types of materials. Dental crowns are generally custom fabricated using indirect methods.

 Types Of Dental Crowns

Permanent dental crowns can be made from stainless steel, all metal (such as gold or another alloy), porcelain-fused-to-metal (also called a PFM crown), all resin, or all porcelain.

-Stainless steel. These short term use dental crowns are  pre -formed metal shells.They are used on permanent or primary teeth generally for a few years, or as a temporary. The temporary crown protects the tooth or filling while a permanent crown is made from another material. For children’s teeth, a stainless steel crown is commonly used to fit over a  tooth that’s been prepared to fit it. The crown covers the entire tooth and protects it from further breakdown. This type of dental crown also serves another purpose, to hold space in the mouth for the permanent teeth to move into. When the primary tooth eventually falls out of the mouth, the crown comes out with it.

-Metal Alloy. These dental crowns can include crowns made of gold , other precious alloys (for example,platinum, palladium), or a base-metal alloy or non-precious (for example, nickel or chromium). Purer gold is the softest yet easiest to get ideal fit, while non precious crowns are variable in hardness and strength. Non precious dental crowns tend to make the underlying tooth black as,over time, metals leach into the tooth, they may also have a very metallic taste.  Metal dental crowns can be made very thin. This allows for minimal tooth structure to be reshaped in preparation for the crown. Another advantage is, that metal crowns are not as hard as porcelain. This “softness” causes much less wear on the opposing tooth. Metal dental crowns do not break or chip and tend to withstand biting forces well over time. However, metal crowns are not very cosmetic, can wear through, and generally are reserved for the areas not visible in the smile line.

Dental Crowns Marielaina Perrone DDS-Porcelain-fused-to-metal (PFM). These dental crowns are the most widely and commonly used. They have the benefit of good fit and underlying strength from the metal.The underlying metal alloy may be any combination of precious or non precious as mentioned above. These dental crowns are more cosmetic, and are fabricated to match the color of the surrounding teeth. However, the porcelain outer layer will cause more wearing to the opposing teeth than a metal crown. The porcelain portion of the crown can also chip or break off over time. PFM dental crowns can be highly esthetic and look just like your natural teeth when prepared properly. Over time, with gum recession, a dark line may become visible at the gumline. This is the underlying metal of the crown. Depending upon where it is in the mouth, it may become a cosmetic problem. These dental crowns are able to be used for any teeth in the mouth.

-All ceramic, all porcelain, all resin. These dental crowns are the ultimate in cosmetic crowns. These provide better natural color match than any other crown type. These are also a good choice for patients with metal allergies of any kind. However, some are not as strong (example, Belle Glass) as porcelain-fused-to-metal crowns, some are stronger (example, Bruxzir crowns). These dental crowns tend to wear down opposing teeth more than metal crowns would. Because of the lack of metal, there will never be a black line to worry about.  All porcelain crowns are the perfect choice for front teeth cosmetics, or any teeth that will be easily seen when smiling.

Dental Crown Tips

So, you have been told you need a crown to restore a tooth? The following are some things to ask or check on with your dentist to ensure you are receiving the highest quality care that will last over the long term:

-American Made? Many dentists  save costs by resorting to using dental laboratories overseas in places like Costa Rica and China. They tend to be made with cheaper materials and lower quality recycled dental metals and porcelain. Ask your dentist where your crown is being fabricated, along with the laboratory slip to tell how much gold content or type of porcelain is being used.

-How long should it last? Is there any warranty for breakage? Dental crowns generally last between 10-15 years with proper oral hygiene, if a dental crown is madeDental Crowns Marielaina Perrone DDS with inferior materials you can expect breakdown in half that time. Some labs will warranty a crown for up to a year. Especially important if you have chosen a ceramic, resin, or porcelain type crown. ask your dentist about this.

-Lab Created Provisional Dental Crowns. Sometimes to help you make decisions especially in a cosmetic area, a dentist may have a dental laboratory make a trial or provisional crown. This type of dental crown is generally made if there is healing required before the final processing of your new crowns. With lab created temporaries, you can literally see what your permanent crown (shape and color) will look like and whether it blends well with your smile. It also helps you determine if it is compatible with the health of your gum tissues and whether or not you can eat and talk normally. With a provisional crown (as opposed to a routine temporary crown), all the details are worked out ahead of time. There usually is an additional charge for this extra step as there will be a laboratory fee involved as well as extra chair time with dentist. Once you approve, your final crown is custom made to match the blueprint provided by the provisional, except that the final materials are stronger, of better quality, and look far more natural.

-Always ask to see the crown before it is placed permanently in the mouth! This should be something most dentists do anyway but not all will. You want to ensure shape and color are to your liking before it is placed in permanently. If the color is off or does not feel right voice your concerns. If you truly are not happy with something that cannot be adjusted chair side ask for the crown to be remade. Crown aesthetics can be very subjective, and their beauty is very much in the eyes of the beholder. Both your input and your dentist’s professional experience should come together in giving you the smile you want.

Conclusion

Each and very dentist has a professional responsibility to treat to the standard of care for a particular dental procedure. Even if some dentists may use inferior products or dental laboratories they are still responsible that the dental crown fits properly and functions as it should.

Not all dental crowns are made the same,and not all dentists, or their labs, have the same skill, training, or experience. A well trained dentist will have no problems preparing and inserting a good functioning dental crown. It takes a skilled dentist and lab to make it look natural, without anyone knowing you even have a crown in your mouth. Dentistry ultimately is an art and choosing the right dentist for you will create a happier, healthier smile.

 

Tooth reshaping, or dental contouring, is a very conservative and fairly inexpensive option to help improve the overall cosmetic appearance of your smile. If you have a

Tooth Reshaping For A More Cosmetic Smile!

minor issue or defect in your smile that you want to fix, tooth reshaping could be for you. Tooth reshaping is a cosmetic dentistry procedure that can make small subtle changes to your teeth that can give huge results to a patient’s appearance and self confidence. This technique removes small amounts of tooth enamel in order to change the shape, length, or surface of one tooth or multiple teeth. This procedure is often combined with dental bonding, another cosmetic dentistry procedure that uses tooth-colored composite material to re contour and shape the teeth.

Smile imperfections or problems like slightly overlapping or irregularly shaped teeth, tiny chips in the teeth, or excessively pointy cuspids, can often be fixed with a little tooth reshaping and dental contouring.

The Procedure of Tooth Reshaping

Tooth reshaping is completed utilizing dental instruments and abrasion techniques. X-rays may be needed before the reshaping and contouring begin to ensure that your teeth are otherwise in a healthy condition. Your cosmetic dentist will then highlight areas that need sculpting and re contouring. A sanding instrument is used to gently eliminate or minimize imperfections on the surface of the teeth. Sandpaper-like strips may be used to contour the sides of the teeth. Finally, the teeth are polished back to their original shine. Only you and your cosmetic dentist should know any work was done.

Advantages of Tooth Reshaping

-Minimal Cost. Tooth reshaping is inexpensive and a great way to improve the look of your teeth. Tooth reshaping can cost as little as $50-100 per tooth.

Example of Before and After Tooth Reshaping

-Zero Pain or Discomfort. During tooth reshaping only surface enamel is removed so there is generally no pain or discomfort involved. No anesthesia is needed.

-Improves overall dental health. Removing minor overlaps and other imperfections where tartar and plaque can build up can lower your risk of tooth decay and periodontal disease. The teeth will be easier to keep clean when access is easier.

-Possible substitute for orthodontics (braces). In some cases, tooth reshaping and dental contouring can substitute for braces since they make edges of teeth look a little straighter and eliminate minor overlapping. The overall effect will not be as dramatic as a completed orthodontic case but it can give quite an esthetic improvement.

Disadvantages of Tooth Reshaping

-Minor changes. Unlike other cosmetic dentistry procedures, tooth reshaping and dental contouring will not dramatically alter the look of your smile or whiten your teeth. For a bigger change you may consider a true smile makeover, which can include teeth whitening, porcelain veneers, and porcelain crowns. Tooth reshaping and dental contouring can only remove small imperfections, whereas porcelain veneers cover the entire front surface of the teeth, giving them a completely new look, shape, and color.

-Possible risk of damage to teeth. Tooth sensitivity could be an issue depending on how much enamel is removed during the tooth reshaping. Also, if too much enamelHenderson Cosmetic Dentist Marielaina Perrone DDS is removed during tooth reshaping there can be an increased risk for fracture or breakage down the road.

Tooth Reshaping: Is It Right For You?

Tooth reshaping and dental contouring are best for people who require just minor changes or repairs to improve the cosmetic look of their teeth. However, dental reshaping and tooth contouring are not appropriate for people with decaying teeth, root canals, or unhealthy gums.

Many times tooth reshaping and dental contouring are the first steps toward more extensive cosmetic dentistry work. Procedures such as porcelain veneers, teeth whitening, and crown lengthening can be completed months or even years after tooth reshaping.

If you want to avoid the time and expense of major cosmetic dentistry, tooth reshaping and dental contouring could be just the answer to a better smile. It is oftentimes  a great way to improve dental hygiene and give you a boost of self confidence. As always, see your dentist regularly for dental examinations and professional cleanings to maintain a healthy, beautiful smile for a lifetime!

 

Porcelain crowns have been a staple in cosmetic dentistry for years. It gives the dentist and patient a much more aesthetic appearance as a final product. In the past crowns and bridges were traditionally made of porcelain fused to metal (PFM). With the development of modern porcelain, which are incredibly strong and reflect light similar to natural teeth, full porcelain crowns can be used in most areas in which porcelain fused to metal crowns were used. This is especially true in a cosmetic area of the mouth.

Porcelain crowns are very versatile and used in many ways. The cosmetic enhancement use of porcelain crowns include, changing color of teeth, closing gaps between teeth, fixing teeth that are crooked or crowded, changing shape or size of teeth. Porcelain crowns are also used to cover and protect damaged teeth, (tooth that has a root canal, broken, cracked, large fillings), and to act as a new tooth in the case of dental implants. Their versatility gives the dentist 89014 a greater flexibility in using them to fix potential issues for the patient.

The first step often times includes impressions for study models and photos. The patient and dentist can then discuss and plan what the end result should be. The treatment includes preparation of the tooth surface for the porcelain crowns. The outer enamel and sometimes a bit of  the dentin are removed. This allows room for the porcelain crowns to fit over the teeth and be in perfect cosmetic alignment with the others. Impressions are taken of the newly reshaped teeth and temporary crowns are made.  The porcelain crowns are custom made in the dental laboratory. The porcelain crowns are then cemented or bonded onto the teeth using an adhesive bonding material. The placement of the porcelain crown will normally take about 30 minutes (depends on amount of porcelain crowns being placed). Once completed,  the patient can eat normally and enjoy the benefits of a beautiful new porcelain crown that matches and blends perfectly with the patients existing teeth. Only you and the dentist should know anything was done.

Advantages of All Porcelain Crowns

-No PFM gray or black lines at the Gum Line of Teeth. You may have noticed a person with a dark line in the gum area along a PFM crown edge. With PFM crowns, the soft tissue around the tooth can recede over time. This allows a reveal of the metal framework underneath. This cannot happen with an all porcelain crowns because they are metal free.

-Perfect Fit. Porcelain crowns are created in state of the art facilities. Porcelain crowns will fit so well you will even forget they are present.

-Cosmetically Perfect Match. All porcelain crowns have the ability with modern porcelains to match your existing shade of tooth color as well as mimic the light reflecting properties of your natural teeth. Porcelain crowns will be undetectable to anyone but you and your dentist. Dental porcelain can be shaped custom colored and sculpted to closely copy the look of your own natural tooth enamel. All the while providing the desired strength and resilience.

Some disadvantages of an all porcelain crowns:

-Higher cost over traditional PFM crowns.

-Durability. While porcelain crowns are very durable, they do not have the flexibility of natural teeth, they can fracture. Avoiding certain foods may be necessary. For example, Biting into sandwich with a hard bread. Patients who grind and clench their teeth will need to be fitted with a mouth guard to protect the porcelain crown from unnecessary and excessive pressures.

-Porcelain crowns may need a bit more reduction of tooth structure than traditional PFM crowns.

-Sensitivity may happen for a short time, (hot, cold sensitivity), especially with bonded porcelain crowns.

Follow-up Maintenance of All Porcelain Crowns

The maintenance of porcelain crowns is actually very easy.  They require routine brushing with non-abrasive fluoride toothpaste and regular flossing as well as regular visits to the dentist. A follow-up appointment will be scheduled to evaluate the porcelain crowns about 2-4 weeks after they are placed in the mouth This allows the dentist to review the work with tissues all healed and see how your oral tissues are reacting to the crowns. Even if you think the crowns are successful, this appointment is an important part of your future oral health.
There are several types of all porcelain crowns generally used in dental offices today. They have all proven to give the best cosmetic dental results.
-Zirconia Crowns or Lava Crowns (made by 3M Espe). This type of all porcelain crowns are made out of a zirconium core with porcelain pressed or layered over the crown to follow the natural contours of teeth. These crowns offer good strength and durability. Due to great strength, the material can be used to make a bridge.
-Procera Crowns (made by Nobel Biocare). These are made of an Alumina core with porcelain pressed or layered over the crown to follow the natural contours of the teeth. These crowns offer great strength and durability and are esthetically quite beautiful. Often used in the back of the mouth, (premolars, molars), these are cemented in with traditional cement and have less post-placement sensitivity.
-Empress II Crowns (made by Ivoclar Vivadent).These highly cosmetic porcelain crowns are used in the front of the mouth. They are used mostly for cosmetics, are very beautiful, but can fracture.
-eMAX Crowns or IPS e.MAX Crowns (made by Ivoclar Vivadent). These porcelain crowns are entirely made out of porcelain without a underlying framework. The absence of this framework offers a great advantage over Zirconia crowns, Lava crowns and Procera crowns in that e.MAX crowns allow for more light transmission through the crown translating to a more superior cosmetic dental result. The strength of these porcelain crowns is such that they can be used in any area of the mouth, can be made thinner than most porcelains, and can be used for an implant without much worry of fracture.
Cosmetic Dentistry is the art and science of creating a beautiful smile. The all porcelain crowns are just one more tool that the dentist can use to give you that smile you’ve always dreamed of.
