Common Denture Problems and When to See Your Dentist

Dentures restore your smile and your ability to eat and speak. But like any medical device, they can develop problems over time. Some issues resolve with simple home care. Others require professional attention. This guide helps you recognize the difference. For a complete overview of denture types, see our main guide: Dentures: A Complete Guide to Partial and Full Tooth Replacement Options.

Why Do Dentures Become Loose? Understanding Bone Resorption

Dentures become loose primarily because of bone resorption. When natural teeth are lost, the jawbone no longer receives stimulation from chewing forces. The bone slowly shrinks over time. This is a normal, predictable process. Most patients experience measurable bone loss within the first 6-12 months after extractions, followed by slower ongoing resorption at a rate of 1-2 millimeters per decade.

Loose dentures are not a manufacturing defect. They are a sign that your mouth has changed and your denture needs to be adjusted to match those changes. A properly fitted denture should not rock, tilt, or spin when you bite or chew.

Solutions for loose dentures:

• Denture reline (chairside or laboratory): The dentist adds material to the tissue side of the denture to fill gaps created by bone loss. This restores fit without making a new denture.
• Denture rebase: The entire pink gum-colored base is replaced while the existing teeth are kept. This is useful when the base is worn or cracked.
• New dentures: When bone changes are extensive (typically after 7-10 years), a new denture is more cost-effective than repeated relines.
• Implant-supported dentures: For patients who want to stop bone resorption entirely and eliminate looseness, 2-4 dental implants can anchor the denture permanently.

For residents of Baton Rouge, St. George, and Shenandoah, Dr. Bonaventure offers same-day chairside relines for patients with moderately loose dentures. The procedure takes about 30 minutes and costs significantly less than new dentures.

Painful Sores Under Dentures: Normal vs. Problematic

Not all soreness is the same. Understanding the difference helps you decide whether to wait, use home care, or call your dentist immediately.

Normal Adjustment Soreness (Wait and Monitor)

• Diffuse, aching discomfort across the gums, not concentrated in one spot
• Mild tenderness that improves when dentures are removed
• Resolves within 24-48 hours of reducing wear time
• No visible ulcer or open sore
• Responds to salt water rinses and overnight removal

Problematic Sore Spots (Call Your Dentist)

• Sharp, stabbing pain in one specific location
• Visible red, white, or ulcerated area on the gum matching a denture pressure point
• Pain that worsens the longer you wear your dentures
• Sore that does not improve after 24 hours of denture removal
• Bleeding or discharge from the sore area

Why you should not ignore problematic sores: A denture that constantly rubs the same spot causes hyperplasia – excess tissue growth. Over years, this can develop into a fibrous lump that requires surgical removal before new dentures can be made. In rare cases, chronic irritation has been linked to dysplastic (pre-cancerous) tissue changes.

Dr. Bonaventure schedules same-day adjustment appointments for patients with painful sores. Most adjustments take 5-10 minutes and provide immediate relief. Do not attempt to sand or grind your dentures at home – this destroys the fit and voids any warranty.

Clicking Sounds When Eating or Speaking: Causes and Fixes

Clicking sounds from dentures are embarrassing and distracting. The noise occurs when the denture base lifts off the gum and snaps back down during chewing or speaking. Several factors cause clicking.

• The denture is too loose: The most common cause. When the denture does not fit closely, it rocks with every movement.
• The teeth are misaligned: If the artificial teeth do not meet evenly, the denture pivots on high spots, creating a clicking sound.
• The base is too thick in the palate: A thick denture base reduces tongue space and can click against the tongue during speech.
• Poor muscle control (new denture wearers): Your tongue and cheek muscles are learning new positions. Clicking often resolves within 2-4 weeks as you adapt.

Solutions: For loose dentures causing clicking, a reline restores fit. For occlusal (bite) problems, Dr. Bonaventure adjusts the biting surfaces of the teeth. Do not try to fix clicking by applying more adhesive – this masks the problem without solving it.

Gagging With Upper Dentures: When to Adjust vs. When to Adapt

A gag reflex is a natural protective mechanism. The soft palate (the back part of the roof of your mouth) is highly sensitive. Upper dentures cover most of the hard palate and extend slightly onto the soft palate to create a suction seal. For patients with sensitive gag reflexes, this extension triggers gagging.

Try these techniques before asking your dentist to shorten the denture:

• Insert dentures while looking down at the floor (this relaxes the soft palate)
• Suck on a hard, sugar-free candy or throat lozenge for 2-3 minutes before inserting
• Place a pinch of table salt on your tongue before inserting
• Breathe deeply through your nose and exhale slowly through your mouth after insertion
• Wear dentures for gradually increasing periods (start with 2 hours, add 30 minutes daily)

When to see your dentist: If gagging persists beyond 2-3 weeks despite these techniques, the denture may extend too far posteriorly (toward your throat). Dr. Bonaventure can shorten the back border of the denture by 2-3 millimeters, which usually resolves gagging. However, shortening reduces suction, so a trade-off exists between retention and gag control.

Bad Breath (Halitosis) With Dentures: Causes and Solutions

Persistent bad breath in denture wearers is almost always caused by improper cleaning. Dentures are porous on a microscopic level. Bacteria, yeast, and food debris accumulate in these pores, producing foul-smelling compounds.

Common causes of denture-related bad breath:

• Not removing dentures at night: Wearing dentures 24/7 prevents saliva from washing away bacteria and allows fungal overgrowth.
• Using toothpaste on dentures: Toothpaste is abrasive and creates microscopic scratches that trap bacteria.
• Not cleaning the tissue side of the denture: The surface against your gums collects the most biofilm.
• Not brushing your gums and tongue: Even with full dentures, your oral tissues need daily cleaning.
• Denture stomatitis (fungal infection): Red, inflamed gums under the denture, often accompanied by a white coating on the denture base.

Solutions: Remove dentures nightly and soak in water or denture cleanser. Brush dentures daily with a soft denture brush and mild dish soap or hand soap (not toothpaste). Brush your gums, tongue, and palate with a soft toothbrush. If bad breath persists despite proper cleaning, schedule an appointment to rule out denture stomatitis, which requires antifungal treatment.

When to See Your Dentist: A Decision Guide

Some denture problems can wait for your next scheduled appointment. Others require immediate attention. Use this guide.

Can Wait for Regular Appointment (Schedule within 2 weeks)

• Gradually loosening dentures over several months
• Mild, generalized soreness that improves with overnight removal
• Minor clicking that does not affect eating
• Staining or cosmetic changes
• Bad breath that improves with better cleaning

Call Same Week (Schedule within 3-5 days)

• Sharp, localized sore spot that prevents wearing dentures
• Denture feels suddenly much looser (may indicate broken base)
• Persistent gagging that has not improved after 3 weeks
• Clicking that interferes with eating or causes embarrassment

Call Immediately (Same Day or Next Day)

• Denture cracked or broken in half (may cause sharp edges that cut your mouth)
• Metal clasp on partial denture broke (the sharp end can injure gums)
• Sore spot that is bleeding or has discharge
• Sore that has not healed after 7-10 days of not wearing dentures
• Denture is lost (the longer you go without wearing, the more the fit changes)

Frequently Asked Questions About Denture Problems

Q: Can I fix a cracked denture at home with super glue?

A: No. Super glue contains toxins that leach into your saliva and can cause tissue burns. The glue also creates a brittle bond that fails quickly. Take both pieces to your dentist for professional repair using medical-grade acrylic.

Q: How often should dentures be relined?

A: Most patients need a reline every 2-3 years. Some patients with rapid bone resorption (due to osteoporosis, certain medications, or bruxism) need annual relines. Dr. Bonaventure checks fit at your annual exam and recommends reline when needed.

Q: Can dentures cause oral cancer?

A: Dentures do not cause cancer. However, poorly fitting dentures that create chronic sores and irritation over many years have been associated with increased risk of dysplastic (pre-cancerous) tissue changes. This is why well-fitting dentures and regular dental exams matter.

Q: Why do my dentures smell even after cleaning?

A: Persistent odor despite cleaning suggests you are not removing dentures overnight or you are not cleaning the tissue side thoroughly. Try soaking dentures overnight in a 1:1 mixture of water and white vinegar (rinse thoroughly before wearing). If odor persists, the denture material may be degraded and replacement may be needed.

Q: Can I sleep with my dentures in?

A: No. Sleeping with dentures increases risk of fungal infections, accelerates bone loss, and raises the risk of aspiration pneumonia (inhaling the denture or bacteria into your lungs). Remove dentures every night for at least 6-8 hours.

People Also Ask About Denture Problems in Baton Rouge

How much does it cost to reline dentures in Baton Rouge? Chairside relines typically cost $200-$400. Laboratory relines (more precise) cost $400-$800. Most dental insurance covers relines every 2-3 years.

Can dentures be tightened without relining? No. The only way to tighten a loose denture is to add material to the tissue side (reline) or replace the base (rebase). Adhesives are a temporary mask, not a fix.

How do you treat sore spots from dentures at home? Remove dentures for 24-48 hours. Rinse with warm salt water twice daily. Apply benzocaine gel (Orajel, Anbesol) for pain. If the sore does not heal within 7 days, see your dentist.

Why do my lower dentures never stay in place? The lower jaw has minimal surface area for suction. Muscle movements from the tongue and cheeks constantly dislodge lower dentures. Two dental implants can transform lower denture retention permanently.
