How strong are veeners? A doctor said it is very thin and not strong. Would a composite bonding be stronger?

Dental veneers are the greatest way to restore teeth with minor structural teeth damage. Though, the porcelain veneers are thin, but they are really strong. Its composition make them resistant to develop chips and cracks. The veneers are made with the highest quality porcelain veneers. This will surely transform your teeth appearance and get your radiant smile back to you.

Veneers are a great way to enhance the aesthetics and function of teeth, but their strength relies upon healthy teeth structure, how your teeth come together, any habits that could dislodge or harm your veneers, how well you take care of them, and the design and preparation of them. As you can see, there are a lot of variables that come into play, which is why a consultation with a dentist that is trained in veneers is important prior to deciding what restorative option might fit best for your case.

Porcelain veneers are quite thin but when bonded to the enamel of your tooth, they become very strong. If you do not have sufficient enough  enamel,  the bond strength decreases.   Composite can be a durable restoration in some situations, but it is not as strong or stain resistant as porcelain. If your dentist thinks your teeth need root canals, I would guess that your teeth either have very large fillings that are near the nerve or very deep decay near the nerve. If this is the case, then placing veneers or bonding on these teeth would most likely fail.  Veneers are usually only placed on the front surface of the tooth, not on the inside  surface.   If the inside surface is also in need of repair, then crowns would probably be a better choice to restore your teeth.

Hi:
Porcelain veneers can be quite strong, specially if made out of emax.  Composite is not as strong as a porcelain veneer.
