Why Do My New Dentures Hurt, Slip or Click, and How Long Until I Adjust?
New dentures hurt, slip or click? Learn the common causes, how long adjustment takes (weeks to months), safe adhesive use, and when to call your dentist.

Quick answer
New dentures often hurt, slip or click because your gums and muscles are still adapting and small fit or bite errors show up with real use. The American Dental Association says new dentures may feel awkward for a few weeks. Cleveland Clinic says adjustment can take weeks or months. Follow-up visits are normal.
The first days can feel discouraging, but most of what you feel has a cause, and most causes have a fix. This guide covers each symptom, how long adjustment takes, safe adhesive use and when to call.
Why do new dentures hurt?
New dentures hurt mainly because they press on one area of gum more than another, or because they move while you chew and talk. Cleveland Clinic says dentists look for any areas that put excess pressure on your gums, and that it usually takes several office visits to reach the right fit (Cleveland Clinic, 2023).
The ADA says it is not unusual to have minor irritation or soreness with new dentures (ADA MouthHealthy). A sore spot is a small area where the denture rubs or presses. It is a fit signal, not a sign that you did something wrong.
The ADA adds that ill-fitting dentures can contribute to mouth sores (ADA, 2023), so the fix is an adjustment, not just waiting.
How long does it take to get used to new dentures?
Most people need weeks, and some need a few months. The ADA says new dentures may feel awkward for a few weeks until you become accustomed to them. Cleveland Clinic says it can take weeks or sometimes months to get used to them (ADA MouthHealthy; Cleveland Clinic, 2023).
Stage | What many patients notice | What usually helps |
First days | Fullness, extra saliva, sore spots, awkward speech | Adjustment visit for any sore spot |
First few weeks | Cheek and tongue muscles learn to hold the denture | Follow-up visits, patience, soft foods |
Weeks to months | Chewing and speech feel more natural | Reline or remake if fit still feels off |
Later years | Fit loosens as gums change | Regular checkups, reline or replacement |
Immediate dentures, placed the day teeth are removed, may need more work: the ADA says they may need to be relined or remade after your jaw has healed (ADA MouthHealthy).
Why do new dentures slip or feel loose?
Dentures slip when something keeps them from staying steady against the gum. The ADA says dentures may feel loose while the muscles of your cheek and tongue learn to keep them in place (ADA MouthHealthy). Other causes include ridge shape, saliva, bite and changes in your gums.
Ridge shape: StatPearls says a denture's stability is mainly limited by the condition of the ridge, the bony gum ridge it rests on (StatPearls, 2023).
Muscle control: your tongue and cheeks need time to learn the new shape.
Saliva: saliva helps a denture hold on, and dry mouth can loosen dentures and cause sores, according to a 2024 review (Cureus, 2024).
Bite: an uneven bite can make a denture tip or shift when you chew.
Gum changes: the ADA notes dentures can become ill-fitting as gums change over time (ADA, 2023).
Why do my dentures click when I talk?
Clicking when you speak is a common reason to book a visit, and it is usually fixable. Cleveland Clinic lists "click when speaking" among the signs that dentures need attention (Cleveland Clinic, 2023). The sources we reviewed do not explain the cause in detail.
Clicking is often tied to how the teeth meet or how the denture moves as your lips and tongue work, so the fix varies. Your dentist can check the bite, watch how the denture shifts during speech and adjust it. Do not grind or bend it at home.
How do upper and lower dentures differ?
Lower dentures are usually harder to keep steady than upper ones. A clinical review says the lower arch covers about half the surface area of the upper arch, and the tongue moves against the lower denture's edge. It calls the lower (mandibular) denture usually more problematic than the upper (maxillary) one (StatPearls, 2023).
Upper denture | Lower denture | |
Surface area | Larger, includes the palate | About half as much, per the review |
Palate and tongue | Palate adds support area | Mobile tongue works against it |
Typical feel | Often steadier | Often moves more |
This is a general pattern, not a rule.
What should you know about denture adhesive and zinc?
Denture adhesive can help, but it should not be used to cover a poor fit. The FDA says a large amount of adhesive will not necessarily address problems with ill-fitting dentures, and advises a dentist check the fit (FDA, 2018).
On zinc, the FDA says too much zinc in the body can cause problems such as nerve damage, especially in the hands and feet. It has not found conclusive evidence that these problems result from using zinc-containing adhesive as directed. The FDA advises:
Do not use more adhesive than recommended.
Follow the label, or ask a dental professional if the directions are unclear.
Stop and contact a physician if you notice numbness or tingling.
Know that zinc-free products exist if you prefer to avoid zinc.
The FDA adds that a 2.4-ounce tube should last seven to eight weeks for someone with upper and lower dentures. If you finish tubes faster, tell your dentist. The ADA notes that the American College of Prosthodontists advises avoiding zinc-containing adhesives as a precaution (ADA, 2023).
Symptom, likely cause and fix: a quick guide
Use this table to describe your problem clearly at your appointment. It matches common symptoms to their usual causes and fixes. These are general patterns, not a diagnosis, and only an exam can show what is happening in your own mouth.
Symptom | Likely cause | Usual fix |
Sharp or pinching sore spot | Pressure point on the gum | Targeted adjustment by your dentist |
General soreness over the whole ridge | Uneven bite or healing gums | Bite check, soft foods, follow-up |
Denture lifts when you eat | Ridge shape, bite, muscle learning | Adjustment, practice, possible reline |
Looser in dry mouth | Less saliva film | Ask your dentist or doctor about dry mouth, then recheck fit |
Clicking when speaking | Teeth meeting or denture shifting | Bite and fit check |
Fit worsens months later | Gums and bone change | Reline or replacement |
Sore that does not heal | Needs an exam | See your dentist or doctor promptly |
Do relines help, and how often are they needed?
A reline adds new material to the inside of the denture so it fits your changed gums again. The ADA says a denture that fits poorly, meaning it feels loose or causes discomfort, may need to be relined or replaced. Cleveland Clinic suggests a reline every one to two years (ADA, 2023; Cleveland Clinic, 2023).
The ADA page also lists more than five years since the denture was made as a time to have it evaluated. See our dentures page and our guide to how much dentures cost.
When to call right away
Most denture soreness can wait for a scheduled adjustment, and a short phone call is fine for routine fit questions. These signs should not wait for a regular visit, so call the office or your doctor as soon as you notice any of them:
A sore or irritation that has not healed in two weeks. The ADA says to call your dentist right away (ADA MouthHealthy).
Sharp pain that does not ease or keeps getting worse.
Swelling, fever or pus near the denture. These can be signs of infection. Cleveland Clinic lists swelling, fever and pus among the signs of a tooth abscess (Cleveland Clinic, 2026).
A cracked or broken denture. See our guide to broken denture repair.
Numbness or tingling in your hands or feet if you use zinc-containing adhesive. Stop the product and contact a physician.
Mention your denture when you call. Our emergency dental care team can help you decide how soon to be seen.
Some signs mean urgent care. Cleveland Clinic says to head to the nearest emergency room for a tooth abscess with facial swelling, a fever of 100.4 degrees Fahrenheit (38 degrees Celsius) or higher, or trouble swallowing. We would use the same caution for a swollen, painful mouth near a denture. Call 911 for trouble breathing.
Could implant-retained dentures help?
Implant-retained dentures are an option when a conventional denture keeps moving. Cleveland Clinic says they typically offer more stability than traditional dentures and do not need denture glue (Cleveland Clinic, 2023). They snap onto or attach to implants placed in the jaw (Cleveland Clinic, 2022).
There are trade-offs. The same source says you need surgery, three to six months of healing on average, and enough jawbone to hold the implants. The page lists infection and nerve damage as risks, usually minimal, and says the overdenture needs replacing every 15 to 20 years. Not everyone is a candidate, and a conventional denture remains a sound choice for many people. Compare the two styles in our post on snap-in vs. fixed implant dentures or read about implant-supported overdentures.
How we approach this at Gardens
At Gardens Implant & Cosmetic Dentistry, a denture visit starts with listening: where it hurts and when it slips. Dr. Hans Almanzar, DDS, then examines the gum tissue under the denture, checks how the teeth meet and watches how the denture moves when you talk and chew.
From there, the options are usually small adjustments first, then a reline or a remake if the fit still does not work. If a conventional denture keeps moving, we also discuss implant support, using an exam and 3D imaging to check your bone. The decision is yours, and we explain the trade-offs on both sides.
Frequently asked questions
How long does it take to get used to new dentures?
The American Dental Association says new dentures may feel awkward for a few weeks. Cleveland Clinic says it can take weeks or sometimes months, with several office visits to reach the right fit. Your own timeline depends on your gums, your muscles and how well the denture matches your mouth.
Is it normal for new dentures to cause sore spots?
Minor soreness is common, and the ADA says it is not unusual. A sore spot usually means one area of the denture presses too hard on the gum. Your dentist can adjust that spot, often in a short visit. Do not file or bend the denture yourself.
Is denture adhesive safe to use every day?
Used as directed, adhesive is a common aid. The FDA says too much zinc in the body can cause nerve damage, but it has not found conclusive evidence that zinc-containing adhesive used as instructed does. Follow the label, track how fast you use a tube, and ask your dentist if you need more.
Why do my lower dentures slip more than my upper ones?
Lower dentures usually have less gum area to rest on, and the tongue moves against them. One clinical review says the lower arch covers roughly half the surface area of the upper arch. That is why lower dentures often feel less stable, and why some patients ask about implant support.
When should I see my dentist about denture pain?
Call if a sore does not heal, pain keeps getting worse, or the denture feels loose or clicks when you speak. The ADA says to call right away if a sore or irritation lasts longer than two weeks. Go to an emergency room for facial swelling, fever or trouble swallowing.
Can implants stop my dentures from slipping?
Often they help. Cleveland Clinic says implant-retained dentures typically offer more stability than traditional dentures and do not need denture glue. They do require surgery, healing time and enough bone, so they are not right for everyone. A consultation can show whether you are a candidate.
