Even the best‑fitting dentures can develop problems over time. Sore spots, looseness, cracks, stains, and clicking sounds are common complaints – but most have straightforward solutions. Ignoring these issues leads to discomfort, poor nutrition, and even more expensive repairs down the road.
This guide covers the most frequent denture problems, why they happen, and what you (or your dentist) can do to fix them. We also explain the difference between a reline, a rebase, and a repair – and how to know when it is time to replace your dentures entirely. Whether you live in Chickasha, Altus, Wichita Falls, Mustang, Norman, or Oklahoma City, these solutions apply to your situation.

Key Takeaways (TL;DR)
- Sore spots are normal in the first month: Dentists can quickly adjust high spots. Persistent sores after adjustment may indicate a poor fit.
- Looseness is caused by bone resorption: A hard reline (every 2–3 years) restores fit without making new dentures.
- Never use superglue on a cracked denture: It is toxic and ruins professional repair. Take it to your dentist for same‑day or lab repair.
- Stains require professional cleaning: Ultrasonic cleaners remove calculus that home brushing cannot.
- Dentures need replacement every 5–10 years: Relines extend life, but worn teeth and micro‑cracks eventually require new prostheses.
Sore Spots and Gum Irritation
Sore spots are the most common complaint after getting new dentures. They occur when a small area of the denture base presses too firmly against the gum tissue. While some soreness is expected during the first week, persistent or sharp pain indicates a problem.
- High spot on the denture base: Your dentist uses pressure‑indicator paste to mark the sore spot, then polishes it down. Instant relief.
- Overextended flange (denture edge too long): The dentist shortens the border. This also helps with gagging on upper dentures.
- Sharp clasp on a partial denture: The metal arm is adjusted or polished.
- Fungal infection (denture stomatitis): Red, inflamed gums under the denture. Treated with antifungal medication and better overnight removal.
💡 Home care for sore spots: Rinse with warm salt water (1 tsp salt in 8 oz water) 2–3 times daily. Remove dentures for at least 4 hours per day to let gums heal. Never use over‑the‑counter numbing gels – they can mask a serious fit problem.
Looseness, Rocking, and Slipping
Over time, the jawbone naturally resorbs (shrinks) because it no longer receives stimulation from tooth roots. As the bone changes, the denture that once fit perfectly becomes loose. This is not a manufacturing defect – it is a biological reality.
- Soft reline (temporary): Chairside procedure adding a cushion liner. Lasts 6–12 months. Good for immediate dentures.
- Hard reline (permanent): Lab‑processed acrylic layer replaces the old fitting surface. Lasts 2–3 years.
- Rebase: Entire denture base is replaced with new acrylic while keeping the same teeth. Used when the base is worn but teeth are fine.
- Denture adhesive (temporary fix): Only for occasional use. If you need adhesive daily, you need a reline.
- Denture rotates or falls out when yawning.
- You cannot eat without adhesive.
- Multiple relines no longer help.
- Solution: New dentures or implant‑supported overdentures.
Cracks, Chips, and Broken Dentures
Acrylic dentures are durable but not indestructible. A drop onto a hard surface, a fall, or years of use can cause cracks or complete fractures. The good news: most dentures can be repaired.
⚠️ Never use superglue, epoxy, or any household adhesive on your denture. These products contain toxic chemicals that can leach into your mouth. They also make professional repair impossible because the glue cannot be removed without damaging the acrylic. If your denture breaks, put the pieces in water and call your dentist immediately.
Many dental practices in Chickasha, Norman, and Oklahoma City offer same‑day emergency repair for simple fractures. Call ahead to confirm.
Staining, Calculus, and Bad Odor
Over time, dentures can accumulate stains from coffee, tea, red wine, tobacco, and pigmented foods. Calculus (hardened plaque) can also form, especially on partial dentures near natural teeth. Bad odor often indicates bacterial buildup.
- Prevention: Daily brushing and overnight soaking in a denture‑cleaning solution.
- Light stains: Soak in a denture tablet (Efferdent, Polident) for 15–30 minutes, then brush.
- Heavy stains or calculus: Professional ultrasonic cleaning at your dentist. Do not attempt to scrape off calculus with metal tools – you will scratch the denture.
- Persistent odor: Soak overnight in a 50/50 mix of water and white vinegar once weekly. Rinse thoroughly before wearing. If odor remains, see your dentist – it may be a fungal infection.
If your denture has become permanently discolored or the pink acrylic has turned orange/brown, it may be time for a replacement. Denture acrylic can absorb stains over many years.
Clicking Sounds and Speech Difficulties
Dentures that click during speaking or eating are not only embarrassing but also indicate a fit problem. Clicking usually means the denture is moving vertically or rocking on a pivot point.
- Overextended posterior border (upper denture).
- Insufficient retention from bone loss.
- Premature contacts (bite is too high on one side).
- Loose denture base that rocks.
- Dentist adjusts the denture borders.
- Reline or rebase to improve fit.
- Adjust the bite (occlusal equilibration).
- Consider implant‑supported dentures for permanent stability.
For speech issues (lisping, whistling, or slurring), practice reading aloud for 15 minutes daily. Most people adapt within 2–3 weeks. If problems persist, the denture tooth position may be incorrect – your dentist can evaluate and adjust.
Relines, Rebase, or Replacement – What Is the Difference?
Understanding these terms helps you discuss options with your dentist.
How to know it is time for a new denture rather than a reline:
- The teeth are worn flat or have lost their natural contours.
- The pink acrylic is cracked in multiple places or has changed color.
- You have had 2–3 relines already and the denture still does not fit well.
- The denture is more than 7 years old (full) or 10 years old (partial).
Frequently Asked Questions
People Also Ask
- Can a denture be repaired if it breaks in half? Yes, most complete fractures can be repaired in a dental lab. Success depends on having all pieces and no missing acrylic.
- What causes dentures to turn pink or orange? Usually from tobacco, coffee, or red wine stains absorbed into the acrylic. Professional cleaning may help; otherwise, replacement is needed.
- How do I fix a denture that keeps falling out? Do not rely on adhesive. See your dentist for a reline or evaluation for implant‑supported dentures.
- Is it normal for dentures to hurt after several years? No. Pain indicates poor fit from bone loss. A reline should resolve it.
- Can I get my dentures tightened without relining? No. Tightening (adjusting clasps on partials) can help temporarily, but looseness from bone loss requires a reline.
