Baby Tooth Turned Grey After a Fall - Should I Worry?
If your child’s baby tooth has turned grey after a fall, it can be unsettling. A colour change may happen when the tooth has been bruised or the soft tissue inside the tooth has been affected by the injury.
This guide explains why a baby tooth can turn grey, what signs parents should watch for, when monitoring may be suitable, and when a dental check is important.
If your child has facial swelling, heavy bleeding, a knocked-out permanent tooth, trouble breathing, serious facial injury, or seems very unwell, seek urgent medical or dental help. For urgent dental concerns, see our urgent dental care page for children and families.
Why this guide exists
Why does a grey baby tooth after a fall worry parents?
Parents often notice the colour change after the child seems fine again. The fall may have happened days or weeks earlier, and the tooth may slowly turn grey, purple, brown or darker than the other teeth.
This page helps parents understand what a grey baby tooth can mean, what warning signs to watch for, and when a dental visit is useful. It supports our pages on gentle dental care for children, mouth injury and dental trauma advice, and first visit dental check-ups.
Quick answer block
Is it normal for a baby tooth to turn grey after a fall?
A baby tooth can turn grey after a fall or bump because the tooth has been traumatised. The colour change may be related to bruising inside the tooth, changes in the nerve or blood supply, or healing changes after the injury.
A grey baby tooth does not automatically mean the tooth must be removed. Some are monitored if there is no pain, swelling, gum pimple, infection sign or increasing looseness. However, the tooth should be checked if symptoms appear or if you are unsure what happened during the fall.
Who this guide is for
Is this guide for my child’s grey baby tooth?
This guide may help if your child has had a fall, bump, playground accident or mouth injury and one baby tooth has changed colour.
A front baby tooth has turned grey
Front baby teeth are commonly affected when young children fall forward or bump their mouth.
The tooth changed colour later
The tooth may not change colour immediately. Parents may notice it days, weeks or sometimes longer after the fall.
The tooth is grey but not painful
A grey tooth without pain may still need monitoring because symptoms can change over time.
You are worried about the adult tooth
Baby tooth trauma can sometimes affect the developing adult tooth, depending on the injury and the child’s age.
Core explanation
Why can a baby tooth turn grey after a fall?
Inside each tooth is soft tissue called the pulp. After a knock or fall, the blood supply and nerve tissue inside a baby tooth may be bruised or disrupted. This can lead to a grey, purple, brown or darker colour compared with the nearby teeth.
Colour alone does not tell the whole story. Dentists also look at pain, swelling, tenderness, looseness, gum changes, bite changes and whether the tooth has moved position.
Internal bruising
The tooth may look grey because the tissue inside the tooth has been affected by the impact.
Nerve response
The nerve inside the baby tooth may recover, remain quiet, or become unhealthy over time.
Delayed colour change
The colour can change gradually, so parents may notice it after the original injury seems forgotten.
Different from an adult tooth injury
Baby teeth and adult teeth are managed differently. A knocked-out baby tooth should not be replanted.
Important parent note
If a baby tooth has been knocked out completely, do not put it back into the socket. This is different from a permanent adult tooth, where urgent action can be time critical. Read our knocked-out tooth steps for parents if you are unsure whether the tooth is baby or adult.
What parents often notice
What do parents usually notice after a baby tooth injury?
Parents often notice more than the colour. These small details can help the dentist understand how the tooth is responding after the fall.
“The tooth is darker than the others”
The tooth may look grey, purple, brown or yellow compared with the neighbouring teeth.
“It happened weeks after the fall”
Colour change can appear later, not always on the day of injury.
“The tooth is a little loose”
Some mobility can occur after trauma, but increasing looseness should be checked.
“There is a small pimple on the gum”
A gum pimple near the tooth may suggest infection or a draining sinus.
“My child avoids biting with it”
Avoiding the tooth may suggest tenderness or discomfort.
“The tooth looks pushed in or moved”
Displacement after trauma should be assessed, especially if the bite has changed.
Decision block
Should a grey baby tooth be monitored, checked or treated?
The right next step depends on your child’s symptoms, the type of injury, how loose the tooth is, whether the tooth has moved, and whether there are signs of infection.
| What you notice | What it may mean | What to do next |
|---|---|---|
| Grey tooth but no pain or swelling | The tooth may be stable but still needs monitoring. | Arrange a dental check and follow-up as advised. |
| Tooth is painful to touch or bite | The tooth or surrounding tissues may still be inflamed. | Book an assessment, especially if pain persists. |
| Gum pimple, swelling or bad taste | Infection may be present around the baby tooth. | Seek dental advice promptly. |
| Tooth is very loose or has moved position | The tooth may have had a more significant injury. | Have the tooth assessed, especially if the bite feels different. |
| Heavy bleeding, facial injury or child unwell | There may be broader trauma or medical concerns. | Seek urgent care or call 000 if symptoms are severe. |
Urgent signs
When should parents seek urgent advice?
Seek urgent dental or medical advice if your child has facial swelling, fever, a gum abscess, heavy bleeding, significant mouth injury, a tooth pushed into the gum, a tooth that has moved badly, or a knocked-out permanent tooth.
What we commonly see
What do we commonly see when a baby tooth turns grey?
At EasyCare Family Dental, parents often come in because the child is comfortable, but the colour change is worrying. In many cases, the appointment is about checking stability, infection signs, the bite, the gum and whether follow-up is needed.
We also commonly see parents who are worried about the adult tooth developing underneath. This is a sensible concern, and follow-up may be recommended depending on the injury.
A grey tooth with no pain
The tooth may be monitored if there are no unfavourable signs.
A child who seems completely fine
Children may not complain, so visual changes can be the first clue parents notice.
A need for follow-up
Follow-up helps monitor colour, gum changes, mobility and comfort over time.
Follow-up timing matters
Your dentist may recommend follow-up visits after a baby tooth injury to monitor colour, tenderness, gum changes, tooth mobility, bite changes and comfort. This is important because a tooth can look stable at first, then change later.

FAQ
FAQs about a baby tooth turning grey after a fall
These answers are general and are designed to help parents decide when a grey baby tooth should be professionally assessed.
Why did my child’s baby tooth turn grey after a fall?
A baby tooth can turn grey after trauma because the soft tissue inside the tooth has been bruised or affected by the injury.
How long after a fall can a baby tooth turn grey?
A baby tooth may change colour within days, weeks or sometimes later after the injury. Parents should arrange a dental check if colour change appears or if symptoms develop.
Is a grey baby tooth always infected?
No. A grey baby tooth is not always infected. Infection is more concerning if there is pain, swelling, a gum pimple, bad taste, fever or increasing looseness.
Should I take my child to the dentist if a baby tooth turns grey?
Yes, a dental check is sensible. The dentist can assess the tooth, gum, mobility, bite and whether follow-up is needed.
Will a grey baby tooth go white again?
Sometimes the colour may improve, but not always. The more important issue is whether the tooth remains comfortable, stable and free from infection signs.
Does a grey baby tooth need to be removed?
Not always. Removal may be discussed if there is infection, pain, severe looseness, poor position or risk to the developing adult tooth.
Can a baby tooth injury affect the adult tooth?
It can in some cases. The risk depends on the child’s age, the type of injury and how close the baby tooth root is to the developing adult tooth.
What signs should I watch for after a baby tooth turns grey?
Watch for pain, swelling, a pimple on the gum, bad taste, fever, increased looseness, tooth movement, or your child avoiding biting on that tooth.
What should I do if a baby tooth is knocked out completely?
Do not reinsert a knocked-out baby tooth. Keep the child comfortable and seek dental advice. If you are unsure whether it is a baby or adult tooth, seek urgent advice.
