Although getting veneers can give you a beautiful, white smile, there are a few things you should be aware of before making the decision. Firstly, porcelain veneers are designed to be pretty much permanent (they last for between 12 and 25 years), so if you have any regrets afterwards, it could be difficult to undo them. Veneers can also make your teeth more sensitive to hot and cold temperatures. To top it off, it’s important to note that veneers don’t work for all dental problems. If you do have failing teeth or major damage, talk with your dentist about other options.
