Dental veneers are not appropriate for everyone or every tooth. Case selection is an extremely important factor in the success of this technique. Veneering teeth is not a reversible procedure if tooth structure must be removed to achieve your desired result. Only an examination by your dentist can determine whether dental veneers are appropriate for making the changes you want. Some of the situations where certain teeth or people are not good candidates for dental veneers include:
Dental decay and active gum disease must be treated prior to fabricating and bonding dental veneers.
If a significant amount of tooth structure is missing or has been replaced by a large filling, the teeth will not be strong enough to function with a dental veneer.
Teeth with an inadequate amount of enamel present.
Dental veneers are more successfully bonded onto tooth enamel.
People who habitually clench or grind their teeth.
Habitual clenching and grinding of the teeth can easily chip or break dental veneers. Dental night guards may be a solution for this in some cases.
Persons without a stable bite.
Severely malpositioned teeth or misaligned teeth.
Orthodontic treatment may be required to achieve the desired result.
