You get hit, catch an elbow during a game, or take a tumble, and suddenly your tooth feels all odd. It’s not exactly aching, but it’s not quite right either. When your tooth feels strange after a knock, it’s a pretty clear sign of some sort of dental trauma, and just what you do from here may make all the difference.
- Any tooth that gives you a weird feeling after a hit, be it sore, loose, sensitive, or like it’s been bruised, needs a dentist to take a look at it within 24 to 48 hours, even if all appears okay on the surface.
- Emergency warning signs to watch out for include a tooth that’s been knocked out or is loose as a goose, severe pain, swelling that’s getting out of hand, numbness in the area, or just won’t stop bleeding.
- For starters, take care of the immediate pain and discomfort by chomping on soft foods, steer clear of biting down on the injured tooth, apply a cold compress to bring down the swelling, take some over-the-counter painkillers if it’s safe, and store that broken tooth fragment in some milk.
- Even seemingly minor hits can leave ‘hidden damage’ such as pulp injury, damage to the blood vessels, or a fractured root, which might not show up right away, but may cause serious oral health issues down the road, so get in to see a dentist ASAP to prevent root canal treatment or tooth loss down the line.
What’s Going On When Your Front Tooth Feels ‘Weird’ After a Hit?
When your tooth takes a hit, whether it’s from falling off a bike, playing a sport, or just biting down on something hard—that can cause damage even if nothing appears wrong on the surface. It’s called dental trauma, and it can affect the teeth, gums, surrounding tissues, or your jaw. Over time, internal nerve damage might show up as tooth discoloration, but even a relatively minor impact can knock the periodontal ligament askew. That’s the tiny web of fibers linking the tooth root to the bone—think of it like a sprained ankle where pain or damage exists under the surface.
Different sensations can point to different problems, such as:
- A dull, constant ache: could be a bruised tooth or just a twisted ligament.
- Sharp pain when biting down: indicates a crack or fracture, probably.
- Feeling like your tooth is loose or longer than usual: might be a sign that it’s got displaced in the socket.
- Hot or cold sensitivity: could indicate a crack or irritation to the pulp.
Front teeth take a lot of hits, and if you’ve got persistent tooth pain, then it could mean the nerve inside the tooth is in trouble. Even if it’s just a little bit off, it’s still worth getting it seen to by a dentist.
When Do You Need to Rush To Get Emergency Dental Care
Some injuries can wait a day or two, but others need to get immediate treatment to keep the tooth.
Get Immediate Dental Care If:
- Your tooth has gone missing
- Your tooth has been pushed way out of position, or into the gum
- Your tooth feels loose
- Your jaw won’t budge, or you have difficulty chewing after a suspected jaw injury
Get in to see an urgent care dentist if:
- Your tooth is in agony
- Swelling’s getting out of hand
- You can’t stop bleeding in your mouth
- You’ve got numbness or tingling around the injury
- You’ve got a pretty big crack in the tooth that’s exposed pink or red tissue
If a tooth feels strange after a hit, get in to see a dentist as soon as possible, especially if it’s darkening, bleeding a lot, getting looser, or swelling up. Even if it’s just a bit sore or chipped, it still needs to be seen by a dental professional ASAP.
If you’ve got major facial trauma, then head to the emergency department first to get things sorted out, then follow up with a dentist.
The Immediate Care Steps You Need to Take After You Hit Your Tooth
What you do right after getting your tooth knocked out (or in) can make a huge difference to whether the tooth survives or not, especially if it’s one of your front teeth.
What to Do Right Off the Bat When You’ve Injured Your Tooth
- Rinse your mouth out with cool water to clear out any debris and then use a warm salt water solution to keep the area clean.
- Apply a cold compress to the cheek for ten to twenty minutes at a time to bring down the swelling.
- Don’t go biting down on the affected tooth; that’s just going to make things worse.
For a Chipped or Fractured Tooth
- Find the piece and save it. Rinse it carefully and store it in milk or a saline solution, as your dentist might be able to stick it back in place.
For a Completely Knocked-Out Tooth
- Pick it up by the crown; don’t touch the root. If it’s dirty, rinse it gently. If you can reinsert it yourself, then go for it, but right away, get yourself to a dentist. If you can’t get it back in, then find a safe place to keep it moist.
Taking the Pain Down a Notch
Cold compresses and over-the-counter painkillers such as ibuprofen or acetaminophen can help, but don’t go sticking aspirin right on your gums, as that can burn a hole right through it.
What to Avoid
- Eating anything hard, sticky, or crunchy
- Wiggling or poking the tooth
- Taking very hot or cold drinks if you’re feeling sensitive
The Various Types of Dental Trauma Symptoms And What They Feel Like
When your tooth feels weird, it can be any number of things hiding beneath the surface. Here are some common ones to look out for.
Bruised tooth/ligament sprain: So, the tooth hurts when you bite down and may feel like it’s stuck a bit higher in your mouth than it should be. That usually sorts itself out within a few days, and you should be eating soft food for a bit. A tooth can take on a bit of a grey or pinkish tinge after a whack; if it goes grey, it could mean the nerve is dead.
Loose tooth (subluxation or luxation): The tooth feels pretty loose or even moves when you run your tongue over it, and it might feel like it’s a bit longer than it should be. Even if it doesn’t feel like too much is wrong, it’s a good idea to get to the dentist ASAP and probably get something called a splint fitted to help it heal.
Fractured tooth: Smaller chips can leave you with sharp edges or sensitivity, but if it’s a bit deeper, you might get pain when you bite, temperature sensitivity, or have the nerve exposed, which makes a big infection risk.
Displacement injuries: If one of your teeth gets nudged inwards, outwards, or sideways, it can mess up your bite and cause a bit of discomfort.
Children’s teeth: If a kid hits their front teeth, it’s always a good idea to get the dentist to take a look; even if they seem fine, there can be complications lurking beneath the surface.
Hidden Damage: Pulp Injury, Root Fractures, and Root Resorption
Not all the symptoms of tooth trauma show themselves right away. Pain that hits a few days, or even weeks, after the fact can mean there’s some underlying damage.
Pulp damage: A whack to the tooth can knock the pulp out of line, causing sensitivity or pain or a weird discoloration in the tooth. You might get some swelling, a bad taste, or a little pinkish bump on the gum, and if the pain is throbbing, get on the phone to the dentist ASAP.
Root fractures: These can just make your tooth ache a lot, feel a bit loose, or hurt when you bite, and sometimes only a special X-ray can spot one of these fractures. If it reaches the pulp, they might need to do a root canal.
Root resorption: After a big whack, the body can start breaking down the root of the tooth, slowly over a couple of months or a couple of years; you might be able to catch it with follow-up X-rays.
If you catch it early enough, a dentist might be able to do a root canal, fit a splint or other treatment to help save the tooth before you can lose it.
What Your Dentist Will Do After Dental Trauma
Once you seek professional care, your dentist is going to be trying to sort out the pain, protect the tooth and stop anything getting worse.
Initial check-up: They’ll want to know what happened, take a look at the tooth and gums to see if it’s loose, cracked, moved out of place, or if the soft tissue around it is damaged. They’ll also check your bite to be sure everything is still working as it should.
Imaging (X-rays): They might take some X-rays to see if there’s any bone damage, or a root fracture or early signs of root resorption that you can’t spot with your own eyes. Here are some common treatments for each type of injury:
| Injury | Treatment |
| Small chips or cracks | Dental fillings are used for minor chips and cracks; smoothing sharp edges |
| Larger fractures | Composite bonding or crowns |
| Loose or displaced tooth | A custom splint may stabilize a dislodged tooth against neighboring teeth |
| Pulp damage or nerve damage | Root canal therapy removes damaged pulp to save the tooth |
| Severely damaged teeth | Tooth extraction is recommended for severely damaged teeth |
| Infection | Infection may require antibiotics and drainage of an abscess |
Follow-Up and Home Care: Helping an Injured Tooth Recover
Some dental injuries need monitoring for months or even years. The American Association of Endodontists recommends checking in at 4 weeks, 6–8 weeks, 4 months, 6 months, 1 year, and then every year up to 5 years if you get a root fracture. If things do go wrong, you might need things like veneers, crowns or even implants to fix things up.
Most minor injuries will heal on their own if you look after them properly, but supplementing your dental care with some good home care is essential.
Daily care tips:
- Eat soft food and chew on the other side of your mouth so as not to put too much pressure on the tooth.
- Don’t go wiggling the tooth or trying to see if it’s still attached; that can make things worse.
- Cut back on grinding or clenching and talk to your dentist about a night guard if you find you’re doing it.
- Use a cold compress a few times a day for the first 24 to 48 hours.
- Brush gently with a soft toothbrush, but avoid flossing too hard around the injury.
Bruised teeth or ligament sprains usually sort themselves out within a few days, but if the pain gets worse, the tooth starts going funny colours, or you notice any other changes, get back to the dentist ASAP.
Prevention is key: Wear a mouthguard if you play contact sports, don’t chew ice or hard objects, and sort out any bruxism you might have.
FAQ
How long will a tooth be sore after being hit?
Bruising or ligament pain usually settles within a week, though tenderness when biting can last up to two weeks. If pain persists, worsens, or appears days later, see your dentist.
Can a loose tooth tighten back up on its own after an injury?
Sometimes, if the ligaments and bone are intact and the tooth isn’t under too much strain. Still, have a dentist check it; splinting may be needed. If it gets looser, get help ASAP.
Do I always need a root canal after dental trauma?
No. Many bruised or chipped teeth heal on their own. A root canal may be needed if the pulp is dead or infected, especially with severe pain, swelling, or discoloration.
Is it safe to keep playing after a sports injury?
If your tooth aches, feels loose, or is seriously damaged, stop contact sports and see your dentist before playing again. Once cleared, wear a properly fitted mouthguard to protect against further injury.
