Your natural teeth are well protected under your veneers. The surface of your teeth must be filed down to make space for your veneers, and during this filing down process a layer of enamel is removed from your teeth. This means that the tooth is no longer strong enough to go without a veneer.
But because your newly-filed teeth are promptly covered with porcelain veneers, they are even more protected than before, and more stain-resistant, too.
When determining if veneers are right for you, you should also consider the cost of eventual veneer replacement. Even with regular upkeep, your veneers will eventually need to be replaced. For many patients, replacement is not necessary for several years.
Because veneers are a cosmetic dental procedure, many dental insurances do not cover them. Check with your insurance provider to find out what kind of coverage is available to you.
