I have grooves in my front teeth and they do not have enamel. Are veneers recommended for my front teeth?

Without photos or x-rays, I can't give you a true answer, however, if you truly do not have enamel on your front teeth you might be better off with crowns to cover the whole tooth. 

Without seeing pictures, it is hard to say.In general, if there is no enamel left, the remaining portion of the tooth should be covered.Porcelain veneers are often a great option!

Sounds like the perfect situation for veneers.  Your dentist will evaluate the grooves and may suggest a whitening procedure prior to veneers if the grooves are much darker than your surrounding enamel.  They will evaluate your "bite" and check for para-functional habits like tooth grinding/clenching which could add stress to your veneers (not to mention damaging your natural teeth) and make plans for protecting your new dental work.  Post pics if you can, that always helps.

Hi:Most likely veneers are a good option for you as long as there is enough tooth structure remaining.  To give you better advice please post photos of your teeth.Best,Dr. Maddahi
