Do you feel your tongue pressing against your teeth at rest or when swallowing? This sensation deserves description, but does not by itself prove that the tongue is moving your teeth. Assessment should distinguish tongue posture, swallowing movement, bite and any recent dental change.
Identify when the pressure occurs
The first question is simple: is the pressure spontaneous at rest, limited to swallowing, associated with a new appliance or caused by trying to maintain a “correct position”? These are different situations.
Also note whether it is contact without discomfort, persistent pressure or pain. The tongue meeting the teeth during a movement does not establish pathological thrusting. The professional considers this observation within the mouth's overall function.
The guide to resting tongue posture helps distinguish spontaneous observation from a deliberate action.
What we know about the tongue–teeth relationship
Resting tongue and lip pressures contribute to dental equilibrium. Proffit's theoretical paper is a reference on this point. It also emphasises that deviant swallowing is more likely an adaptation than a sole explanation for movement. Proffit, 1978
Avoid two hasty conclusions: “it is all caused by the tongue” and “the tongue has no role”. Assessment identifies which factors are present in your situation. A swallowing video or smile photograph is insufficient to decide.
When should you start with a dental check?
If a gap appears, a tooth seems mobile or the way you close your mouth changes, have this examined. Gum bleeding should also be reported. Assurance Maladie lists mobility and new spaces among possible signs of periodontal disease. Assurance Maladie.
After orthodontics, report the condition of your retainer and the wearing schedule actually followed. Do not try to correct movement by forcing an old appliance. The guide to spaces between teeth explains which observations to bring.
What can retraining address?
If assessment identifies a functional difficulty, work may address a resting reference point, movement precision or swallowing coordination. Exercises should be demonstrated, reproduced in front of the professional and reassessed.
Reviews of myofunctional therapy in orthodontics remain cautious about outcomes. They do not support promising that retraining alone will realign teeth or prevent relapse. Homem et al., 2014
Ask for a verifiable goal: what should be observed at the next review? Fatigue is not the intended result. The guide to tongue exercises explains the different types of work.
Can an appliance help stop the pushing?
A device may be discussed for a defined goal with an appropriate size and instructions. It does not replace assessment or establish that the tongue caused the movement.
The French review of prefabricated appliances highlights limited evidence and adverse effects in some studies. Studied devices are not all equivalent, and results do not automatically transfer to a commercial product. Amat and Tran Lu Y, 2023
Myoforce is a standard moulded tongue retraining appliance. It does not replace a retainer made within orthodontic care. A retainer aims to maintain the result and requires its own checks. Martin et al., Cochrane, 2023
Questions for the appointment
- Does the observed pressure reflect posture, movement or adaptation to my bite?
- Are my teeth or gums showing a change that needs treatment?
- Which retraining goal fits the assessment?
- Do I need an appliance, and which is compatible with my current care?
- How can the result be checked without relying only on sensations?
To choose whom to consult, see physiotherapist or speech and language therapist for the tongue. Bring any appliance and its instructions instead of starting several methods at once.
