I know tongue thrusting against teeth causes tooth movement, will tongue thrusting against the gum just behind incisors cause tooth/ bone movement?

It could: Your mouth is in a steady state with the teeth being held by the bones being shielded by the gums etc. There's plenty of movement going on there already just with eating. Better not to rock the boat by pushing any more with your tongue, grinding the teeth, etc.

Not really: You have to press pretty hard and continually against your teeth to have a moving experience. Think of when an orthodontist puts wires in your mouth pressing on your teeth constantly 24 hours a day for months to move your teeth. Realistically you are not going to be able to do that with your tongue in your mouth.

Tongue thrust: Tongue thrust can,ove teeth. Airway problems, enlarged tonsils can cause an adult tongue thrust. An ENT can evaluate your airway. A speech pathologist can help you with exercises. An orthodontist may also help by improving your bite.

Possibly: It would depend on how close to the tooth you are on the gum. If your tongue is still against the tooth you can get movement from the tongue thrust. A speech pathologist can give you exercises to train your tongue to rest higher on the palate and away from the teeth. A retainer could also be made to be worn at night to prevent tooth movement.

Should be OK: One of the techniques we use in trying to manage a tongue thrust is to relocate the contact from the teeth to the palate just as you describe. While an extreme case could possibly have an un-anticipated effect on the bone, most likely it will be just fine. The key is to have the treating dentist monitor you for unexpected changes.

Unlikely: However, tongue thrusting can be the result of large tongues or obstructed airways. See your dentist or PCP for evaluation and tests.

Possibly: It depends the force and frequency of the tongue thrust and the anatomy of the area. If your teeth are loose and slightly sore, they may being affected. See your dentist or an orthodontist for his opinion.

Yes: The force from the strong tongue muscle can push the teeth outwardly. This can push the teeth away from the ridge of jawbone and thinning the gum tissues. This will lead to excessive recession or gum pulling down away from tooth and bone loss. This will cause tooth loss over time.

Yes: Any abnormal or excessive pressure by the tongue against developing structures can lead to bone or teeth deformities. Consult with your dentist for a possible tongue thrusting habit appliance.

Bone remodeling: Surprisingly there is much less change in the bony contours as a result of tongue thrusting if the pressure is only on the gums behind the teeth. Most bone remodeling is caused by pressure on the teeth stimulating the changes in the supporting bone

See below: Ask your dentist for a referral to an orthodontist for a definitive diagnosis.

Not quickly: What are your symptoms, I'm not sure you gave enough information to evaluate your condition. While in theory, bone could resorb under continued pressure over a period of time, it's important to evaluate each case. If you feel you are experiencing a problem, you should have this evaluated professionally. The solution may be something simple and unrelated.

In over 40 years: I have never seen or heard of this happening, nor read of any scientific reports or findings. Tooth movement? yes. Bone movement/reformation? extremely rare if at all from tongue thrusting.

Tongue Thrust Issues: Good day; The tongue muscles are quite powerful and may easily cause lower anterior tooth flaring. Conscious retraining of the tongue to touch the anterior portion of the upper palate as you swallow or talk may lessen or cure the habit.

Possibly: The younger the patient the more chance of damage to the maxillofacial structures
