The short answer
If your denture teeth and base are in good shape but the denture feels loose, a reline is usually the first step. If the teeth are worn, the base is cracked or the denture is very old, a new denture is often the better choice.
A reline adds new material to the inside of the denture, the side that touches your gums. It brings back the fit without making a whole new denture. Cleveland Clinic recommends a reline every 1 to 2 years, or sooner if the fit changes.
Your dentist makes the final call after looking at the denture and your mouth.
Ask your dentist whether your type of denture can be relined. Most can, but some older materials or damaged bases are not good candidates, and a new set may be the better use of your money.
Why dentures get loose
Your mouth changes after you lose teeth. The jawbone slowly shrinks, and the gums change shape with it. A denture made for the old shape starts to move.
A loose denture rubs your gums and can cause sore spots. It also slips when you talk or eat, which is tiring and can be embarrassing. Many people then use more and more adhesive. That may help for a while, but it is a sign you need a dental visit.
After extractions, the changes are faster. Gums heal and shrink over the first months, so a denture made right after extractions will usually need a reline or a replacement.
Weight loss, illness or a long time without wearing the denture can also change how it fits. Gums can shift even in a few months. If your denture suddenly feels different, do not wait. Early care is simpler.
Take note of what you feel. Does the denture drop when you open wide? Does it move when you laugh or cough? These details tell your dentist which part of the fit has changed.
What a reline is, step by step
Plan on a short break from your denture if a lab reline is needed. Some offices lend you a backup, or ask you to bring your old one. Ask how long you will be without it before you start.
Some relines can be done in one visit. Others need a lab, which takes a bit longer. Your dentist will tell you which is best for your denture. The denture teeth and the outside shape stay the same.
A reline is a simple process:
- The dentist checks the denture and your gums.
- The dentist takes an impression of the inside of the denture with your gums in their current shape.
- New material replaces a thin layer inside the denture, so it matches your gums.
- The dentist checks your bite and adjusts the denture.
Soft and hard relines
There are two common types. A hard reline uses a firm material like the denture base. It is the long-term choice. A soft reline uses a cushiony material, which can help people with very tender gums.
Soft liners can wear down and stain faster, so they may need to be replaced more often. Your dentist will recommend what is best for you.
There is also a short-term kind called a tissue conditioner. It is used to help sore or irritated gums heal before a final reline or a new denture.
Soft relines feel good at first, but they need more care. Clean them gently with a soft brush and skip harsh cleaners, which can break down the liner. Your dentist can tell you how long yours should last.
Whatever type you choose, ask what is included. A reline fee may or may not cover follow-up adjustments, and knowing that up front avoids surprises.
Relines after extractions
If you got a denture right after your teeth were removed, expect it to need a reline. The gums shrink as they heal, so the denture gets loose.
Dental sources say the definitive reline or replacement often comes about 6 to 9 months after extractions, when healing is well along. Some dentists do a temporary reline earlier to help you stay comfortable in the meantime.
Follow your dentist's timeline. Not every mouth heals at the same speed, and the dentist who removed your teeth is the best person to set your plan.
If you wear a temporary immediate denture, a reline may also be the step that keeps you comfortable until you are ready for the final set. Ask whether your office includes early adjustments in the original price, since policies differ.
Keep in mind that a reline is a repair, not a cure. It restores fit for a time, and the gums will keep changing. That is why Cleveland Clinic's advice to reline every 1 to 2 years is a rhythm to plan for, not a one-time fix.
When a new denture is better
Look at the teeth in good light. Flat, worn teeth make chewing harder and can change how your face looks. A new denture can bring back height and shape. Also look at the base. Hairline cracks can spread, and a break in the middle of a meal is no fun.
A new denture also gives you a chance to update the look. If the color, shape or size of your old teeth no longer suits you, say so. A natural shade and shape make a big difference in how you feel when you smile.
If your bite has changed a lot, a reline will not fix it, because the teeth themselves are the problem. In that case, a new set can correct the bite and give you a fresh start.
A reline cannot fix everything. Cleveland Clinic lists these signs that you should see your dentist about a replacement:
- The denture is more than 10 years old
- It is cracked, chipped, stained or discolored
- The teeth are worn flat
- It clicks when you talk
- It hurts or pinches your gums even after adjustments
- Your bite has changed
What about a denture that stays put?
If you reline your dentures again and again and they still feel loose, ask your dentist about implants. A denture held by implants does not depend only on the shape of your gums. Cleveland Clinic says implant-retained dentures are more stable than traditional ones and do not need denture glue.
Implants also help stop bone loss, which is the reason dentures get loose in the first place. They cost more at the start, and you need enough bone. A 3D scan shows what is possible in your case.
You do not have to decide today. Many people choose a reline now and think about implants later.
Some people also choose a middle path. They reline the current denture to stay comfortable while they plan and save for implants. Ask your dentist whether that makes sense for your case.

Common questions
How often should I reline my dentures?
Cleveland Clinic recommends every 1 to 2 years, or sooner if the fit changes.
Can I reline my denture at home?
Store-bought kits are not made for your mouth and can change your bite and irritate your gums. We recommend a dentist do it.
How long does a denture reline take?
Some are done in a single visit, while others need lab time. Your dentist will tell you before you start.
Will a reline change how my denture looks?
The teeth and the outside shape stay the same. The change is on the inside, where the denture touches your gums.
Is a reline covered by insurance?
Many plans cover part of it, with limits on how often. Call your plan or call us with your insurance details and we can help.
