Chipped or Cracked Tooth? Emergency Repair Options Explained

A chip or crack rarely looks as serious as it feels. Sometimes it's a small corner missing from a front tooth; other times it's a hairline crack you can feel with your tongue but can't quite see. Either way, the right next step is the same: get it looked at, because what feels minor on the surface isn't always minor underneath.

This guide covers what usually causes chips and cracks, the repair options available, and how to tell whether yours needs same-day attention, and it sits alongside our main Dental Trauma page. For what to do in the first few minutes after the damage happens, see our dental trauma first-aid guide.

Why a Small Chip Can Matter More Than It Looks

Teeth are strongest with their outer layer of enamel intact. Once that's broken, even slightly, the layer underneath (dentine) is more exposed to temperature, bacteria and further pressure. A chip that seems purely cosmetic today can turn into sensitivity, decay around the rough edge, or a bigger fracture later if it's left unaddressed.

Cracks are the less visible version of the same problem. A crack can run below the gumline or toward the nerve without being obvious from the front, which is why we'll usually want to take a closer look, and sometimes further diagnostics are needed like x-rays, thermal, pressure and transillumination light testing, before telling you how serious it is.

What Causes Chips and Cracks

The usual culprits are biting down on something hard (ice, boiled sweets, a stray bit of bone), a knock or fall, grinding at night, or an old filling that's weakened the tooth around it. Teeth that already have large fillings (particularly old amalgam fillings) are more prone to cracking, since there's less natural structure left to absorb everyday pressure.

Repair Options, Depending on What's Damaged

• Composite bonding. For small chips on an otherwise healthy tooth, we can often rebuild the missing corner with tooth-coloured composite resin in a single visit, with little to no discomfort involved.
• A veneer. If the chip affects the visible, front-facing part of a tooth and the rest of the tooth is sound, a veneer can be a conservative, long-lasting cosmetic fix. We cover how this compares with a crown in our crowns vs veneers guide.
• A crown. Where the damage is more significant, or the tooth needs to withstand normal biting force again, a crown covers and protects the whole tooth rather than just the front surface.
• Root canal treatment, in some cases. If a crack has reached the nerve, or the tooth has become painful or sensitive to temperature, root canal treatment may be needed before any crown or restoration goes on top. Sometimes this is only visibile via microscope, which is a service we provide.

Which option applies to you depends on where the damage is, how deep it goes, and whether the nerve has been affected, so this is always confirmed in person rather than guessed at from a description over the phone.

How Quickly Should You Be Seen?

If there's pain, visible nerve exposure (often a pink or reddish tinge inside the chip), or a sharp edge that's cutting your tongue or cheek, treat it as urgent and call us straight away. A clean, painless chip can usually wait for the next available appointment, but it's still worth booking soon rather than leaving it, since untreated chips tend to get worse rather than better.

In the meantime, avoid chewing on that side, keep the area clean, and use a cold compress if there's any swelling.

What Happens at the Appointment

We'll examine the tooth, check for any nerve involvement, and may take an X-ray to see below the surface. From there we'll talk through the realistic options for that specific tooth, including what each one involves and how it's likely to hold up, before agreeing a plan together.

Frequently Asked Questions

Can a chipped tooth repair itself?

No. Enamel doesn't regenerate, so a chip will stay as it is, or get worse, until it's treated.

Is a chipped tooth an emergency?

Not always. Pain, sensitivity, or a sharp edge make it more urgent; a small painless chip can usually wait for a routine appointment, though we'd still recommend not leaving it too long.

Will I need a crown for a small chip?

Usually not. Most small chips on otherwise healthy teeth can be treated with bonding or a veneer rather than a full crown.

Does composite bonding look natural?

Yes, it's colour-matched to your surrounding teeth and blended in at the edges, so it isn't usually noticeable once finished.

What if I can't find the broken piece of tooth?

That's fine, and common. We don't need the original fragment to rebuild or restore the tooth.
