There are a lot of reasons (including a blow to the mouth) why one of your permanent teeth might become loose. The most common: advanced periodontal (gum) disease that has weakened the gum attachment to the tooth.
There's also another, less common reason: you have a grinding habit that's producing higher than normal biting forces. Besides accelerating tooth wear, the constant jaw movement and teeth clenching can stretch periodontal ligaments and loosen their attachment to a tooth.
If the gums are disease-free, teeth grinding is most likely the main culprit for the damage, what we call primary occlusal trauma. Our treatment goal here is to reduce the effect of the grinding habit and, if necessary, secure the teeth with splinting while the ligaments heal. We can often reduce the grinding effect with a custom bite guard worn while you sleep. We may also prescribe minor muscle relaxants and mild pain medication like aspirin or ibuprofen.
Sometimes we may need to perform other measures like re-shaping your teeth's biting surfaces so they don't generate as much biting force. You may also benefit from counseling or other psychological treatment to help you address and cope with stress, a prime driver for teeth grinding.
Even if you don't have a grinding habit, biting forces may still contribute to tooth looseness if you have advanced gum disease. Advanced disease results in excessive bone loss, which in turn reduces the remaining amount of ligaments attached to the tooth. This type of damage, known as secondary occlusal trauma, and ensuing tooth looseness can occur even when your biting forces are normal.
It's necessary in these cases to treat the gum disease, primarily by manually removing plaque and calculus (hardened plaque deposits), which causes and sustains the infection. Once removed, the gums can begin to heal and strengthen their attachment. We may also need to apply splinting or perform surgical procedures to encourage gum and bone reattachment.
Whatever has caused your loose tooth, our goal is to remove the cause or lessen its effects. With your tooth secure and the gums regaining their healthy attachment, we have a good chance of saving it.
