Chipped teeth are one of the most common things we see. A corner of an incisor catches on a fork. A back molar loses a piece while you're eating popcorn. Sometimes it's painful, sometimes it's just a rough edge that drives your tongue crazy. Either way, it's an easy fix — but the more important question is usually why it happened, because the answer changes how we treat it.
One chip can happen to anyone
An isolated chip on an otherwise healthy mouth is usually mechanical: a hard bite on a popcorn kernel or olive pit, a stumble on the sidewalk, an old filling that finally gave way. In these cases the repair itself is straightforward. Depending on the size and location of the chip, we typically use one of three restorations:
- Bonding for small chips on front teeth. We sculpt a tooth-colored composite directly onto the tooth in a single visit. It looks natural, requires almost no removal of healthy enamel, and is often the same-day fix.
- A veneer when the chip is larger, the edge is worn, or there's an aesthetic concern across the whole tooth. A thin shell of porcelain bonds to the front surface and gives a more durable, polished result.
- A crown when a significant portion of the tooth is missing — a cusp broken off a molar, a deep crack, or a tooth that's already been heavily filled. The crown wraps the whole tooth and protects what's left.
Repeated chips are a different story
When the same person chips a tooth twice in a year, or chips three different teeth over time, we stop treating each chip as its own incident and start looking for the underlying cause. In our experience, the answer is almost always one of these:
- Clenching and grinding (bruxism) — Most of the time, the patient is grinding at night and has no idea. The chronic force flattens edges, fatigues enamel, and eventually pieces start breaking off — usually from the front teeth or the corners of molars.
- An uneven bite — When upper and lower teeth don't meet evenly, certain teeth take the brunt of every chew. Over years, that uneven loading creates microcracks that eventually fracture.
- Old, large fillings — A tooth that's been filled multiple times has less of its original structure. The remaining enamel walls become thinner and more prone to fracture under normal chewing.
- Acid erosion — Frequent acidic foods, drinks, reflux, or some medications soften enamel over time. Once enamel is thinned, even normal forces start chipping it away.
When we identify one of these patterns, the repair on the most recent chip is only half the answer. The other half is protecting everything else.
Why a night guard is so often part of the plan
If grinding is contributing — and it often is — a custom night guard is the single most cost-effective protection we offer. It's a precise layer of hard acrylic worn during sleep that absorbs the force your jaw generates and prevents teeth from grinding against each other. We make it from a quick impression in the office and it's ready in about a week.
For patients with stronger clenching habits or jaw soreness on waking, we'll often pair the night guard with targeted Botox into the masseter muscle. The night guard protects the teeth from any grinding that still occurs; the Botox reduces how hard the muscle can clench in the first place. Together they meaningfully slow the cycle of damage. We've written about this combination in more detail in a separate post.
When the chip came from real trauma
If the chip happened during a fall, a sports accident, or any kind of blow to the face, our approach changes. The visible damage is only part of what we need to evaluate. A traumatic impact can injure the nerve inside the tooth even when the outside looks mostly fine, and that injury can take weeks or even months to show itself.
The two warning signs we watch for after dental trauma are:
- Discoloration — The tooth slowly darkens to a gray, yellow-brown, or pinkish shade. This usually means the nerve is dying or has died, and blood pigments have leaked into the dentin.
- Lingering sensitivity or pain — Sensitivity to temperature that doesn't fade, a dull ache that comes and goes, or pain on biting weeks after the incident.
If either shows up, the tooth almost certainly needs root canal therapy to remove the damaged nerve tissue and seal the inside of the tooth. Once a tooth has had a root canal, it becomes more brittle — the nerve and blood supply that kept it flexible are gone. That's why we strongly recommend a crown over root canal teeth, especially molars. The crown wraps and protects the tooth so the underlying treatment lasts for decades instead of fracturing in a few years.
What follow-up looks like after trauma
We don't always do a root canal at the first visit, because the nerve may still recover on its own. Instead we do an exam, take baseline imaging, restore the visible damage, and then re-check the tooth at intervals — usually one month, three months, and six months — watching for color change or symptoms. This way, we treat exactly what the tooth needs, no more and no less.
If you grind, a night guard is also part of the long-term plan after trauma. A tooth that's been compromised once is more vulnerable to a second injury, and protecting it during sleep adds years to the lifespan of whatever restoration you have.
Our take
A single chip is usually a one-visit fix and not something to worry about long-term. Repeated chips are worth a real conversation — not just about the latest tooth, but about the bite, the grinding habits, and the protection going forward. And if the chip came from trauma, please let us know, even if it looks small. The nerve damage that follows trauma is invisible at first, and catching the early signs of it is the difference between a simple bonding and a root canal with a crown several years down the road.
