Why Do My Teeth Keep Breaking? Understanding Worn Dentition

If your teeth keep chipping or cracking, worn dentition may be the reason. Worn dentition is the gradual loss of tooth structure over time, often caused by clenching and grinding, shifting teeth, or an unbalanced bite—common reasons behind worn down teeth and repeated tooth fractures. Dietary habits like frequently eating hard foods (think nuts) or acidic items (like lemons or soda) can also contribute. It may appear as flattening on the biting surfaces or small notches near the gumline, and can lead to sensitivity in some people.

As tooth structure is lost, teeth become weaker and more prone to chipping and cracking, creating a cycle of ongoing damage as forces become less evenly distributed. Careful evaluation of the bite, along with thoughtful planning and precise restorations, can help restore strength while protecting the remaining tooth structure. In some cases, this can be managed conservatively with a night guard, monitoring, or small areas of bonding, while other situations may benefit from approaches like Botox to reduce excessive biting forces or minimally invasive restorations that protect worn teeth. In more advanced cases, a comprehensive full-mouth approach may be needed to restore the bite. No matter the stage of wear, addressing the underlying cause—not just the broken tooth—is key to maintaining a stable, healthy smile.
