Knocked-Out Tooth: What Happens After the Emergency Visit

If you've recently had a tooth knocked out and reinserted, or seen a dentist for emergency treatment following the injury, the first-aid part is behind you. What comes next, and how it's likely to go, is often less well understood. This guide picks up where our dental trauma first-aid guide leaves off, part of our wider Dental Trauma care, covering what recovery actually looks like.

What Happened During the Emergency Visit

If your tooth was successfully reinserted, it was almost certainly splinted, bonded lightly to the teeth either side to hold it steady while the supporting tissue starts to reattach. This splint typically stays in place for a few weeks, sometimes longer, depending on the type of injury and how the tooth responds.

If reinsertion wasn't possible or didn't take, we'll have discussed the alternatives with you directly, which can range from monitoring to a fixed implant, tooth retained bridge, or removable denture further down the line once things have settled.

The First Few Weeks: What's Normal

Some tenderness, mild swelling, and sensitivity to temperature are common in the days immediately after the injury and are not usually a cause for concern on their own. A soft diet, avoiding biting directly on the affected tooth, and gentle brushing around (not on) the area all help the healing process.

It's also normal for a reinserted tooth to feel slightly different, a little loose, or not quite "right" for a while. The supporting ligament needs time to reattach properly, and that doesn't happen overnight.

Signs That Need a Follow-Up Sooner Than Planned

Get in touch before your next scheduled review if you notice increasing pain rather than it settling down, a colour change in the tooth (greying is a sign the nerve may have been affected), swelling that's getting worse, or a bad taste or smell near the area.

These can indicate the nerve isn't recovering as expected, which is treatable but worth catching early.

Root Canal Treatment

For permanent teeth that have been knocked out and reinserted, root canal treatment is common rather than exceptional, particularly once the root has fully formed.

This is usually just how the nerve responds to that kind of trauma, not a sign anything went wrong with theemergency treatment. We'll monitor the tooth at review appointments and only proceed with root canal treatment if and when it's actually needed.

Review Appointments

Expect to be seen again at set intervals, often around two weeks, one month, three months and again at a year, so we can check healing, nerve response and the stability of the tooth over time. These reviews matter even once the tooth feels completely normal again, since some complications only show up later.

Protecting the Tooth Going Forward

Once healed, a tooth that's been knocked out can be more vulnerable to further injury than it was before. If you play contact sport, a properly fitted mouthguard is worth discussing at your next visit, it's a simple way to protect the investment you've already made in saving the tooth.

Frequently Asked Questions

How long does a knocked-out tooth take to heal?

Initial healing of the splint and surrounding tissue is usually a matter of weeks, but full

assessment of nerve health can take up to a year of monitoring.

Will the tooth definitely survive long-term?

Not always, success depends on how quickly it was reinserted after the injury, the type of

injury, and how the nerve responds during healing. We'll be honest with you about the

outlook at each review.

Why has my reinserted tooth gone slightly grey?

This usually indicates the nerve has been affected and may need root canal treatment. It's

worth having checked rather than waiting to see if it resolves on its own.

Can I eat normally with a splint in place?

Stick to softer foods and avoid biting directly on the splinted tooth until it's removed, to avoid

dislodging it while it's healing.

What if the tooth doesn't survive despite treatment?

We'll talk you through the options at that point, which commonly include a bridge or a dental

implant, and there's no rush to decide immediately.

If anything about your recovery doesn't feel right, don't wait for your next scheduled review,

get in touch and we'll take a look. Our Dental Trauma page has more on how we handle

dental injuries and emergencies.
