Improperly fitting dentures can cause mouth damage, including blisters, sores, cuts, and scrapes. These injuries lead to inflammation, bleeding, and increased risk of infection. Ill-fitting dentures may also hinder chewing, resulting in poor nutrition and health problems. Jaw pain caused by poorly fitting dentures can lead to headaches and earaches due to inflammation of the temporomandibular joint (TMJ). A misaligned bite affects facial muscles, leading to TMJ pain and temporomandibular disorder (TMD). TMD limits mouth opening, impacting eating, speaking, and oral health. Book your yearly exam to make sure your dentures still fit you perfectly.
