Teeth that don’t normally hurt, but hurt when chewing can be due to periodontal problems, TMJ pain, dental problems, etc. 1. Periodontal problems: If the patient suffers from periodontitis or gingivitis, chewing harder food will cause obvious pain around the teeth, which will easily give the patient a toothache. 2. Temporomandibular joint pain: the cause of temporomandibular joint pain is usually due to jaw trauma or excessive wear and tear of the teeth, resulting in underbite, the formation of a kind of aseptic inflammation; this disease can also cause patients to chew food when the tooth pain. 3. Dental problems: If the patient suffers from dental caries, it may lead to dental nerve damage and inflammation, which may cause the patient’s teeth not to hurt normally when the inflammation is mild, but there is pain when chewing food with force. If your teeth don’t usually hurt, but you have pain when chewing food, you should consult a doctor in time to avoid delaying your condition.
