Whether a tooth shows signs of decay known as demineralization or has a fully swollen cavity, your dentist will not place a veneer over the compromised enamel. Although these conditions can affect the appearance of your teeth, they must be properly treated before veneers are an option. Treating these problems with veneers will not fix the underlying problems and allow them to worsen. Your dentist will conduct an evaluation to determine if you are a good candidate for veneers or if you need other treatments, such as a dental crown first.
So do veneers fix cavities? No. You can't use veneers to cover dental cavities. Wolfe must remove tooth decay first before considering giving him dental veneers. Another way to avoid problems with veneers is to not use your teeth as tools.
Simply using your teeth to open a package can damage both your teeth and veneers. You should also wear a night guard or mouth guard to protect your teeth from clenching and grinding, and during contact sports. Most problems that occur with veneers can be completely avoided with proper care steps. Finally, teeth can still have cavities while under a veneer, which can lead to root canals and crowns along the way.
Veneers should not be used if you have a history of weakening enamel, gum disease, or other dental conditions. If this is your case, your dentist can recommend other treatment options to repair broken or missing teeth.
