Yes...absolutely! Porcelain veneers or direct composite bonding are often the best way to make small teeth look larger.However larger can mean a lot of things, so your cosmetic dentist has to determine what precisely you mean by larger? Longer? Wider? Thicker or more pronounced? Larger in general shape?You see, cosmetic dentistry is actually an art form and it differs many ways from regular dentistry or orthodontics. Your cosmetic dentist will evaluate many things before he/she recommends or designs your new porcelain veneers:how long your teeth are compared to normal teeth?how wide your teeth are compared to normal teeth?how much of your teeth show when you smile?when your lips are completely relaxed, and your back teeth separated, how much of your upper teeth show below your upper lips?does the shape of your teeth conform to norms of age, gender, facial shape?is there too much gums on your teeth hiding your teeth (actually a excess gum issue and not a tooth size issue)?the size of your jawsany spacing or overlapping (crowding) of your teethAfter your dentist evaluates the above mentioned things he/she can give you recommendations on what could be done. Then, if you agree with your dentist and like the recommendations, it is all up to you. To have cosmetic dental treatment or not? But it all starts with the initial consultation.And one word of advice, not all dentists who say they are a cosmetic dentist are. Find a good cosmetic dentist from their website. Ask to see before and after photos of patients they have ACTUALLY treated. Find out how long they have been practicing, how much experience they have and how much and where they got the cosmetic dental training. Choose your cosmetic dentist wisely!
