Caring for Renton patients at our Port Dover office
See every dental service for RentonMinutes matter
What you do in the first few minutes can make a real difference for a knocked-out tooth.
When an adult tooth is knocked completely out of its socket, the cells on the root surface begin to dry and die quickly. Keeping the tooth moist and getting it back into place, or to a dentist, as soon as possible gives it the best chance of reattaching. Even with ideal care, not every tooth can be saved, but quick action improves the odds.
If this happens to someone in or around Renton, call our Port Dover office immediately. The team can talk you through handling the tooth, whether to try replanting it and how to transport it safely. Head injuries and heavy bleeding take priority, so make sure the person is safe before focusing on the tooth itself.
Immediate steps
Gentle handling protects the root surface.
Handle the tooth correctly
Find the tooth and pick it up by the crown, the white part you normally see, not by the root. If it is dirty, rinse it briefly in milk or with saline or clean water for a few seconds. Do not scrub it, wrap it in tissue, let it dry out or try to remove any tissue fragments attached to the root.
Replant or store it
If the person is conscious, calm and old enough to cooperate, gently push the tooth back into the socket facing the right way, then have them bite on clean gauze or cloth to hold it. If replanting is not possible, place the tooth in milk, saline or the person’s own saliva inside the cheek if they will not swallow it, and get to a dentist quickly.
Baby or adult tooth
The approach is different for children’s baby teeth.
Permanent teeth
For permanent teeth, replanting or getting to a dentist quickly is the priority. Many adult front teeth come in around the early school years, so a child of that age or older may have a permanent tooth knocked out. If you are not sure, keep the tooth moist and call right away so the team can help you decide what to do.
Baby teeth
A knocked-out baby tooth should not be replanted, because doing so can damage the developing adult tooth beneath it. Control the bleeding, comfort the child and call the office for advice. The dentist may want to check the area to make sure no fragments remain and that neighbouring teeth were not injured in the same accident.
At the dental office
The dentist works to stabilize the tooth and assess the damage.
Repositioning and splinting
If the tooth has been replanted, the dentist checks its position and may adjust it. If it arrives in milk or another medium, it may be cleaned and gently placed back in the socket. A flexible splint is often bonded to neighbouring teeth to hold the tooth steady for a period while the supporting tissues heal around the root.
Checking for other injuries
X-rays help confirm the tooth’s position and check for fractures of the root, socket or neighbouring teeth. Cuts to the lips or gums may need cleaning or stitches. The dentist may discuss tetanus protection if the injury involved soil, and antibiotics in certain cases. You will receive clear instructions for care at home afterward. Keep them handy.
Healing and follow-up
A replanted tooth needs ongoing attention.
Care while the splint is in
Eat soft foods, avoid biting on the replanted tooth and brush gently around the splint. Use a soft toothbrush and any prescribed rinse as directed. Avoid contact sports until cleared by the dentist. Call the office if pain increases, swelling develops, the splint loosens or the tooth becomes more mobile instead of settling over time.
Long-term monitoring
Root canal treatment is often needed for replanted adult teeth, usually within a few weeks, because the nerve is commonly damaged. The dentist will schedule follow-up visits and X-rays over months and years to watch for root resorption or infection. Renton patients should plan for these appointments, as long-term monitoring is part of successful treatment.

Knocked-out tooth questions
Have a question about your situation? Our team can help you plan a visit.
How quickly should a knocked-out tooth be replanted?
As soon as possible. The longer the root surface dries out, the lower the chances of successful reattachment. If you cannot replant it, keep it moist in milk or saline and get to a dentist quickly. Call the office on the way.
What is the best way to store a knocked-out tooth?
Milk is a good, widely available option. Saline or the person’s own saliva inside the cheek can also work if they will not swallow the tooth. Avoid tap water for long periods and never wrap the tooth in tissue or let it dry.
Should I replant a baby tooth?
No. Replanting a baby tooth can harm the adult tooth developing underneath. Control bleeding, comfort the child and call the dental office for advice on whether the area should be checked and what to watch for.
Will a replanted tooth last?
Outcomes vary. Some replanted teeth last many years, while others develop problems such as root resorption. Prompt action and careful follow-up improve the chances. The dentist will explain what to expect and how the tooth will be monitored.
Will I need a root canal after replanting?
For adult teeth, root canal treatment is often needed because the nerve is usually damaged by the injury. The dentist will advise on timing, which is frequently within the first few weeks after replanting, depending on the situation.
