A chipped tooth can range from a barely noticeable cosmetic issue to a painful break that exposes the nerve inside your tooth. What happens next depends almost entirely on how deep the chip goes. A small chip limited to the outer layer of enamel may not hurt at all, while a larger fracture that reaches the inner nerve can cause sharp pain, sensitivity to hot and cold foods, and a real risk of infection if left untreated.
How Severity Changes Everything
Your tooth has three main layers. The outermost is enamel, a hard protective shell. Beneath that is dentin, a softer layer that makes up most of the tooth’s structure. At the center is the pulp, which contains nerves and blood vessels. The layer your chip reaches determines your symptoms and your treatment plan.
An enamel-only chip is the mildest type. You might feel a rough or sharp edge with your tongue, but there’s usually no pain because enamel has no nerve endings. These chips are primarily cosmetic, though the sharp edge can irritate or cut your cheek or tongue.
A chip that extends into the dentin layer is more serious. Dentin is porous, so you’ll likely notice sensitivity when eating hot, cold, or sweet foods. The exposed dentin also gives bacteria a direct path deeper into the tooth, which is why these chips need professional repair even if the pain feels manageable.
The most severe chips break through to the pulp. When nerve tissue is exposed, you’ll typically feel significant tooth pain, especially while chewing or drinking anything that isn’t room temperature. A pulp-exposed chip is a dental emergency because infection can set in quickly.
What to Do Right Away
Rinse your mouth gently with warm water to clear away any debris. If you can find the broken piece, place it in a clean container with milk, saliva, or saline solution. Dentists can sometimes reattach fragments, and even when they can’t, the piece helps them assess the fracture.
If the chip left a sharp edge, you can cover it with a piece of sugar-free gum or dental wax to protect your tongue and cheeks. A cold compress held against your cheek near the chip will help with any swelling. Over-the-counter pain relievers can manage discomfort until you see a dentist, but avoid very hot or cold foods and drinks in the meantime, since these can trigger sharp pain if dentin or pulp is exposed.
How Dentists Repair a Chipped Tooth
The repair method your dentist recommends depends on how much tooth structure is missing and which layers are affected.
Dental Bonding
For small to moderate chips, composite bonding is the most common fix. Your dentist selects a resin that matches your natural tooth color, roughens the surface slightly so the material adheres, then sculpts the putty-like resin into the right shape. A curing light hardens it in seconds, and the tooth is polished to a natural finish. The whole process typically takes one appointment. Bonding costs between $100 and $600 per tooth and lasts roughly 5 to 10 years for chip repairs, sometimes longer if the surrounding enamel is mostly intact.
Porcelain Veneers
When a chip is larger or affects a front tooth where cosmetics matter most, a veneer may be a better option. Veneers are custom-made ceramic shells that cover the entire front surface of the tooth. They require removing some enamel to fit, which makes the procedure irreversible. Veneers typically need replacing every 10 to 20 years and cost between $900 and $2,500 per tooth. They also require multiple appointments since the veneer is fabricated in a lab.
Dental Crowns
If a large portion of the tooth is missing, a crown caps the entire visible structure to restore its shape and strength. Like veneers, crowns require removing enamel and involve multiple visits. They’re the go-to option when too little natural tooth remains for bonding alone.
Root Canal
When the chip is deep enough to expose or infect the pulp, a root canal is often necessary before any cosmetic repair. The procedure removes the infected nerve tissue from inside the tooth, and a crown is usually placed on top afterward to protect the weakened structure.
What Happens If You Ignore It
A tiny enamel chip that doesn’t bother you might seem harmless, but even minor chips create rough surfaces where bacteria accumulate more easily than on smooth enamel. Over time, that bacterial buildup can lead to decay that works its way deeper into the tooth.
Larger untreated chips carry a more immediate risk. Bacteria can invade the dentin and eventually reach the pulp, causing an infection called an abscess. In the short term, this means increasing pain and sensitivity. In the long term, the infection can damage the tooth’s root, loosen the tooth, and even spread to surrounding teeth and gums. What might have been fixed with simple bonding can escalate into a situation requiring root canal therapy, or the tooth may need to be extracted entirely. An untreated oral infection can also spread beyond the mouth, which is rare but genuinely dangerous.
Chipped Teeth in Children
Kids chip teeth often, and the first priority is staying calm and checking for bleeding, swelling, or signs of serious injury. Rinse the child’s mouth with warm water, apply a cold compress to the cheek if there’s swelling, and save the fragment in milk if you can find it.
Treatment follows similar principles as in adults. Minor chips get smoothed down or repaired with tooth-colored filling material. Moderate chips may need bonding or a crown. Severe chips with pulp exposure can require a root canal even in children. The dentist will factor in whether the chipped tooth is a baby tooth or a permanent one, since baby teeth that are close to falling out naturally may be managed differently than a permanent tooth that needs to last a lifetime.
How Long Repairs Last
Composite bonding is the least durable option, but it’s also the least invasive and least expensive. For chips specifically, bonding typically lasts 5 to 10 years before it needs touching up or replacing. Bonding used to treat decay with mostly intact enamel can last over 10 years. Porcelain veneers are more resilient, lasting 10 to 20 years. Crowns have a similar lifespan and offer the most structural protection for severely damaged teeth.
How long any repair lasts also depends on your habits. Biting hard objects, grinding your teeth at night, and chewing ice all increase the chance of damaging a repair, or chipping another tooth in the first place.
