Tooth Pain
Is it normal for my tooth to feel loose after a filling or injury?

The short answer
A tooth can feel slightly loose or sensitive for a few days after a filling because the ligament around it gets irritated during the procedure, and this usually settles within a week. After a knock or fall, looseness is different and more concerning: it can mean the tooth has been pushed out of position or the bone around it is damaged, and that needs same-day assessment. If the wobble is noticeable when you push it with your tongue, or it hurts to bite, don't wait it out.
After a filling: mild looseness is usually just irritation
When a dentist works on a tooth, especially if the filling is deep or close to the nerve, the ligament that holds the tooth in its socket can get inflamed. That ligament is what you're actually feeling when a tooth seems loose. It's not the tooth physically shifting, it's swelling in the tissue around the root making the tooth feel slightly higher, sensitive to bite pressure, or vaguely wobbly.
This kind of looseness typically peaks in the first one to three days and fades over a week to ten days. It's more common after a filling that involved a lot of drilling, a bite that needed adjusting more than once, or an injection that was close to the tooth's root. Rinsing with warm salt water and avoiding chewing hard on that side for a few days usually helps.
If the filling itself feels high (you notice it hitting before your other teeth do when you close your mouth), that's a separate issue and one worth fixing quickly, since a high bite keeps the ligament irritated and can make the looseness linger longer than it should.
After an injury: looseness can mean something structural
A knock to the mouth, a fall, biting down on something hard, or a sports impact is a different situation entirely. Real looseness here can mean the tooth has been partially displaced (pushed out of its normal position, even slightly), the ligament fibres holding it in the bone have torn, or in more serious cases the bone itself has a hairline fracture.
Signs that point to genuine injury rather than simple irritation include: the tooth visibly sits differently than its neighbours, there's bleeding from the gum around it, your bite feels different when you close your teeth together, or the tooth is tender to the lightest touch, not just to chewing. Colour change in the tooth over the following days or weeks (it may go slightly grey or pink) can also signal that the nerve inside has been affected by the trauma, even if the tooth still feels stable.
Children's teeth and adult teeth behave differently after trauma. A baby tooth that loosens after a knock is often managed by simply monitoring it. A permanent tooth that loosens needs to be checked properly, because the ligament fibres have a limited capacity to reattach and reattachment is most successful when it's addressed early rather than left.
When to get it looked at, and what happens at the visit
As a general rule: mild looseness after a filling that's improving day by day is fine to watch at home. Looseness after any impact to the face or mouth, or looseness that's getting worse rather than better after a filling, is not something to sit on. A dentist can tell the two apart quickly with a bite check, a gentle wiggle test, and usually an x-ray to see the bone and root.
If the tooth has genuinely shifted, splinting it to the teeth next to it for a few weeks can allow the ligament to heal and reattach, provided it's done soon after the injury. If the nerve has been damaged, root canal treatment may be needed later, sometimes weeks or months after the initial injury, which is why a follow-up check matters even if things feel okay at first.
