My dentist said my teeth are feeling slightly loose because my wisdom teeth are coming through. he said my teeth and gums are healthy so is this why?

Can be: It is possible if they are pushing on the teeth. However it may also be clenching/grinding habit. See the Oral Surgeon for evaluation and diagnosis and options. Good Luck.

May be: Teeth move physiologically due to the shock-absorbing effect of the fibers that anchor the root of the tooth to the bone. There are other reasons that may cause tooth movement like bone loss due to periodontal disease or traumatic occlusion. Wisdom teeth may or may not contribute to the mobility of neighboring teeth depending on several factors.

Bruxism: also known as tooth grinding. Sometimes, adult teeth can feel a bit loose, which is particularly noticeable when you're brushing your teeth in the morning. See your dentist for a custom night guard fabrication.

Oral surgeon: See an oral surgeon to assess the problem. For best results with wisdom teeth, make sure you are evaluated and treated by a board certified oral & maxillofacial surgeon.

Wisdom teeth: Wisdom teeth contribute perhaps 10% to instability of the dentition. An Orthodontist can explain to you all of the growth and development changes occurring at this point of your life that contribute to instability. Grinding, clenching, malocclusion, missing teeth, differential jaw growth, messily migration, passive eruption, etc.
