Should you visit the dentist for cosmetic or oral health reasons?

Health then cosmetic. First and foremost, you should visit the dentist for oral health reasons. Tooth and periodontal health affects the health of your entire body. The dentist should also do a thorough oral cancer screening and check for any and all oral pathology. The dentist and hygienist will advise you on your oral health and give oral hygiene instructions. Oral health always comes first, cosmetic second.

Both and more. Today's dentist is a physician of the mouth. Trained extensively not only in the art of restoring damaged, decayed or missing teeth, the 21st dentist treats periodontal disease, regenerates tissue (bone and gingivia), enhances smiles (& self-esteem), works in the early detection of oral cancer and numerous other systemic diseases. Good oral health is a big part of overall general well being!
