Porcelain Veneers The Basics

• Porcelain veneers can simply be defined as thin
  custom made shells with the shape and color of
  natural teeth used to cover the front part of the
  teeth. These types of veneers mimic the light
  reflecting element of natural teeth.
• Half a millimeter of you enamel is usually
  removed after administration of a local
  anesthetic of your choice. This thickness is
  reflective of the thickness of the veneer that
  will be constructed for fitting. The dentist
  makes a model of the tooth or teeth impression
  and sends to the laboratory for construction.
  Usually you have to go home and come back after
  for two to three weeks to give the laboratory
  ample time for construction of the veneers.

• Some people feel uneasy going home with trimmed
  enamel. Temporary veneers are usually used in
  such cases to make teeth appear uniform. These
  may feel rough and sometimes too big for your
  mouth but it is certainly your decision to make
  whether to have them fitted or not. Where only a
  small portion of enamel is removed, it is not
  absolutely necessary to have temporary veneers
  fitted. Where multiple teeth are trimmed in
  preparation for veneer fitting also, temporary
  veneers may not be required because they will
  probably appear uniform. One trimmed tooth may
  however appear strange and in such a case, insist
  on temporary porcelain veneer.

• Bonding is the name of the process that follows
  after the dentists has received the veneer from
  the laboratory. You will first require to have
  your tooth or set of teeth cleaned, and etched in
  preparation for the veneer fitting. Etching is
  meant to make the surface of the teeth rough
  enough to provide strong bonding. The dentist
  should thereafter examine the fit of the veneers
  by placing it repeatedly onto your tooth and
  trimming it accordingly. Once the desired fit is
  achieved, the porcelain veneer is then cemented
  permanently on to your teeth using special
  cement. Special light beam is placed on the teeth
  activating the chemicals in the cement which
  allows quick healing and causes to harden.

Porcelain Veneers vs. Crowns

• Condition of the lingual surface
• This basically refers to the part of the teeth
  that facing inwards towards the tongue and the
  oral cavity. Porcelain veneers requires the
  lingual surface to be intact for best result.
  This may wear out as a result of dental carries
  and other dental problems. In cases where the
  lingual surface is worn out, dentists usually
  recommends crowns to be used.
• Severity of Dental Carries
• Dental carries simply refer to tooth decay or
  cavities. Where dental carries are severe and
  significant, veneers might not be the best
  option. They bond better in teeth with minimal
  dental carries. Here too, you will be advised to
  make use of crowns
• The thickness of the enamel
• Fitting veneers requires removal of some enamel
  and fitting of veneer with the same thickness as
  the enamel removed. In some patients however, you
  will find very thin enamel thus removing might
  make the teeth too delicate to sustain veneers.
  Some people also have enamel that wears off or is
  eroded over time. For such, crowns will be
  preferred to porcelain veneers.

Porcelain Veneers vs. Crowns (cont.)

• Stability of the Occlusion
• Occlusion simply refers to the contact between
  the mandibular and the maxillary teeth. Veneers
  are usually fitted where the occlusion is fairly
  stable, for occlusion that require significant
  modification ahead of the procedure, crowns will
  work best.
• Teeth Significantly Malposition
• Clausal contact and stability can be better
  achieved with dental crowns. Rotten teeth often
  have lingual surface in abnormal occlusion
  relationships. Veneers work best where there is
  no need of repositioning the major teeth.
• Matching the Color of the Veneers and Crowns
• Porcelain veneers mimic the color of natural
  teeth but in most cases, it is possible for
  people to notice the difference between your
  natural teeth and the teeth with the veneers.
  They should be strongly considered during
  treatment planning. If aesthetic requirements are
  high, best results will be achieved by placing
  crowns. When treating just one tooth, it you will
  require crowns. Veneers will show the difference
  in teeth color which is not a pleasant appearance.

• Advantages
• It goes without saying that porcelain veneers
  provides a stronger and more esthetic look than
  other options such as crowning. This coupled with
  the fact that unlike crowns porcelain veneers do
  not require extensive shaping ahead of the
  bonding process makes them an obvious choice over
  the former.
• When fixing any blemish in your teeth, you will
  certainly require material that best mimics your
  real teeth. Porcelain veneers have this
  capability and it is very hard to tell them apart
  from the natural teeth.
• The human gum tissue is very sensitive but always
  tolerates porcelain veneers better than other
  option. This is a big plus because the ultimate
  goal when fitting veneers is not only to improve
  your outward appearance but also to make you feel
  comfortable with minimal or no complications
  after the procedure.
• There is a variety of teeth color to select from.
  This allows you to get whiter colored teeth where
  previously you had darkened teeth and this will
  obviously improve your self-esteem. Most veneers
  are prone to staining but porcelain veneers are
  stain resistant hence giving you great service
  for a long time before requiring replacement.

• Disadvantages
• The major disadvantage of these veneers is
  probably their permanency. You need a very good
  dentist to fit them because you might have to
  live with bad veneers for a very long time.
  Overtime they may chip or crack and this is not
  repairable. You can only replace the whole veneer
  which is a costly procedure. They are more costly
  than composite resin fillings. The fact that part
  of your enamel is removed might make you
  sensitive to hot or cold food and beverages.
  Another major disadvantage is despite porcelain
  veneers are very expensive, they can still stain
  and get germ diseases.
