National guidance from the Royal College of Surgeons of England on painful TMD in adults puts supported self management first for everyone. That means understanding the condition, gentle jaw exercises, heat, soft foods and breaking habits like clenching. It is simple, low risk and often enough.
Physiotherapy, with jaw exercises and manual therapy, is also worth considering for most types of TMD according to the same guidance. [CONFIRM: physiotherapy referral availability] Medication such as short courses of anti inflammatory painkillers may help during a flare up, and your GP can advise on this.
A splint, which most people know as a night guard, is another option. The guidance says splints are most likely to help muscle related TMD and TMD headaches, are not suitable simply for joint noise, and should be tried for around three months of night time use before judging whether they help. Full coverage hard splints are generally preferred over soft ones.
We should be straight with you about the evidence. A 2024 Cochrane review of 57 trials covering 2,846 people found the certainty of the evidence for occlusal splints and similar treatments was very low. A night guard is not a cure, and we would never promise one. For some people it reduces muscle strain and protects teeth from wear. For others it makes little difference.
Irreversible treatments, such as reshaping teeth to change your bite, are not supported as a way to treat TMD, and we do not recommend them for this purpose. If your problem is severe or does not improve, we can discuss referral to a specialist.
