An adult tooth should never feel loose. A loose tooth can be caused by an injury, advanced gum disease, an infection, or heavy biting forces from clenching and grinding.
The sooner we evaluate a loose tooth, the better the chance of determining whether it can be stabilized and treated.
Avoid wiggling the tooth or chewing on that side until you’re seen. Even if it’s not painful, don’t ignore it. Early treatment can make a significant difference.
