Should dentures touch the roof of your mouth?

Editorial team Published on

Traditional upper dentures must cover the roof of your mouth, but alternative designs can leave it exposed if they are secured with dental implants.

Traditional Dentures

  • Full coverage: Standard complete upper dentures cover the entire palate (the roof of your mouth).
  • Suction hold: This large surface area creates natural suction to keep the false teeth firmly in place.
  • Pressure spread: The design helps distribute the biting and chewing pressure evenly.
  • Drawbacks: Full coverage can reduce your ability to taste food and may trigger a gag reflex.

Palateless Dentures

  • Open design: Also called roofless or horseshoe dentures, these leave the roof of your mouth completely bare.
  • Better taste: Leaving the palate open lets you experience the temperature and taste of food more naturally.
  • Implants required: These designs cannot rely on suction, so they generally require dental implants (or snap-in attachments) for stability.
  • Not for everyone: Without implants, a palateless removable denture lacks stability and tends to slip.

My top denture is too thick. What should I do?

Schedule an appointment with your dentist or denturist to have the appliance professionally evaluated and adjusted, and do not attempt to file or shave down the acrylic yourself.

Why It Happens

  • New appliance adjustment: Your tongue, cheeks, and lips are sensitive and need time to get used to the new shape.
  • Gum and bone changes: As your jawbone shrinks over time, the denture may shift, feel loose, or sit incorrectly, creating a bulky sensation.
  • Manufacturing design: The acrylic base or palate may have been built too thick for structural strength or stability.

What You Should Do

  • Visit a professional: A dentist can safely thin specific areas using specialized dental tools without ruining the suction or weakening the structure.
  • Check for a reline: If the thickness is due to movement from a poor fit against your shrinking gums, a professional reline might be needed instead of reducing the plastic.
  • Wear them consistently: If they are brand new, keeping them in (unless instructed otherwise by your dentist) helps your mouth adapt faster.
  • Avoid DIY fixes: Filing your dentures at home can permanently ruin the fit, break the seal, or crack the material.

What are some signs that dentures are not fitting properly?

Pain, shifting, and sore spots on your gums are common signs that your dentures are not fitting properly.

Common Signs of Poor Fit

  • Slipping or shifting: Dentures move, slide, or lift up when you talk, laugh, or eat.
  • Clicking or whistling: The device makes odd noises while you speak.
  • Sores and irritation: Red, swollen gums, blisters, or painful ulcers develop where the plastic rubs.
  • Trouble eating: You feel pain or difficulty when chewing your food.
  • Speech changes: You develop a sudden lisp or slur your words.
  • More adhesive needed: You must use a lot more denture paste than usual to keep them in place.
  • ** Jaw pain or headaches:** Your bite feels uneven, which strains your jaw joints.

How are dentures supposed to look in your mouth?

Properly fitted dentures should look natural, rest snugly against the contours of your gums, and restore healthy fullness to your facial profile.

Appearance and Fit

  • Natural contour: The gum-colored acrylic base should sit flush against your gums without large gaps, visible tipping, or excessive bulk pushing your lips out unnaturally.
  • Facial support: Good dentures fill out the cheeks and lips. They prevent a collapsed or sunken facial appearance that happens when natural teeth are missing.
  • Balanced bite: The upper and lower teeth should meet evenly when you close your mouth, and the midline of the artificial teeth should line up with the center of your face.
  • Stable movement: Your dentures should stay firmly in place when you speak, smile, or bite down gently. The upper denture relies on light suction against the roof of the mouth, while the lower denture rests on the lower jaw ridge.

Warning Signs of Poor Fit

  • Sliding or clicking: Dentures that shift, slip, or make clicking noises when you talk indicate a loose or uneven fit.
  • Sores and pain: Persistent rough spots, severe rubbing, or painful pressure points mean the appliance needs an adjustment from a professional.
  • Sunken look: If your mouth looks caved in or heavily wrinkled around the lips, the dentures may be too small or worn down.

Why do my dentures hurt the roof of my mouth?

Dentures usually hurt the roof of your mouth because of pressure points, an improper fit, or an underlying fungal infection like Denture Stomatitis.

Common Causes of Pain on the Roof of the Mouth

  • Ill-Fitting or Loose Dentures: As your jawbone and gums change shape over time, the acrylic base may rub too hard or shift against the sensitive tissues of your palate.
  • Improper Bite (Occlusion): If your back teeth do not bite down evenly, it can break the suction of an upper denture and force the hard acrylic base to press excessively into the roof of your mouth.
  • Denture Stomatitis (Thrust/Yeast Overgrowth): Wearing your dentures all day and night or failing to clean them properly can trap fungi like Candida underneath the plastic, leading to redness, soreness, and white or red patches.
  • Trapped Food Particles: Small pieces of food or debris can slip under the palate of the denture and create sharp friction against the soft tissue.
  • New Appliance Adjustment: If your dentures are brand new, your mouth may simply still be getting used to the pressure of the artificial material.

How to Find Relief

  • Take Them Out at Night: Always remove your dentures before sleeping to give your gum tissues and palate a chance to rest and breathe.
  • Soak and Clean Daily: Clean your dentures with a soft-bristled brush and soak them overnight in a proper cleaning solution to kill bacteria and fungi.
  • Rinse with Salt Water: Warm salt water rinses can help soothe irritated tissue and keep any sore spots clean.
  • See Your Dentist: If the pain lasts more than a few days, visit your dentist to have the appliance adjusted, relined, or checked for infection.

Should dentures push your lips out?

Dentures should provide mild support to fill out your lips, but they should not push them out so far that your mouth looks strained or bulky.

Why Dentures Push Lips Out

  • Teeth Placement: Front teeth set too far forward make the upper lip project too much.
  • Thick Acrylic: Too much pink plastic behind the lip creates an extra bulge.
  • Bite Height: A vertical bite height that is too high holds your jaws too far apart.
  • Recent Extractions: Swelling after new tooth removal can temporarily make immediate dentures look very thick and puffy. Most users on Reddit agree that this swelling goes down after a few weeks.

How It Should Feel

  • Your lips should close easily and comfortably without straining.
  • Your lower face should look natural, not puffy or overly full.
  • You should avoid the sunken, collapsed look known as denture face, which happens when teeth or bone are too small.

What can you never eat again with dentures?

You can still eat most foods with dentures, but you must permanently avoid or heavily modify extremely sticky treats like chewing gum and caramel that pull appliances loose.

While few foods are strictly forbidden forever, certain items require permanent changes in how you prepare them or eat them.

Foods to Avoid or Modify Completely

  • Chewing Gum & Sticky Candies: Caramels, taffy, and gummies grip the acrylic teeth and create a pulling force that dislodges the plate. Gum is exceptionally difficult to clean off prosthetic material.
  • Popcorn Kernels & Small Seeds: Popcorn hulls, sesame seeds, and poppy seeds slip underneath the denture base and press against sensitive gum tissue like a pebble in a shoe.
  • Corn on the Cob: Biting straight into corn puts uneven leverage on front teeth and can flip the appliance out of your mouth. Alternative: Scrape the kernels off the cob first.
  • Tough, Fibrous Meats: Thick steaks and jerky require heavy lateral chewing force that destabilizes lower dentures. Alternative: Slow-cook, tenderize, or finely chop your meat.
  • Hard, Crunchy Raw Produce: Whole raw carrots and unpeeled apples risk cracking the acrylic or causing sore pressure spots. Alternative: Steam vegetables or slice fruits into thin, bite-sized pieces.

Why can't I close my lips with dentures?

You cannot close your lips easily with new or ill-fitting dentures because the acrylic base and teeth are often too bulky or positioned incorrectly, forcing your lips to stretch or strain over the extra material.

Common Causes

  • Initial Bulkiness: New dentures add foreign material to your mouth, making your lips and cheeks feel overly full until your facial muscles adapt.
  • Incorrect Tooth Position: If the artificial teeth or acrylic flange (the pink base) are set too far forward or made too thick, your lips cannot meet naturally.
  • Vertical Dimension Issues: If the bite height of the dentures is built too high, it keeps your jaws slightly forced apart, preventing a relaxed lip seal.

How to Fix It

  • Give It Time: If your dentures are brand new, your lips and mouth muscles typically adjust to the fullness within a few weeks.
  • See Your Dentist: If the problem persists or causes strain, discomfort, or dry lips, your dentist or denturist can safely adjust, reshape, or re-evaluate the acrylic base and bite alignment. You can learn more about managing fit issues through resources like Pinnacle Smiles.

Which is easier, top or bottom dentures?

Top dentures are much easier to wear, stabilize, and adapt to than bottom dentures.

Why Top Dentures Are Easier

  • Natural suction: The upper plate covers the roof of your mouth (the palate), creating a strong suction seal that holds the denture firmly in place.
  • Larger surface area: More skin and bone contact spreads out chewing forces, giving the upper set a major mechanical advantage.
  • Less movement: The upper jaw does not move, and surrounding facial muscles do not interfere much with the fit.

Why Bottom Dentures Are Harder

  • No suction: The lower jaw has no roof, meaning a bottom denture cannot use suction to stay secure.
  • Tongue and muscle interference: Your tongue, cheeks, and lips move constantly when you speak and eat, which frequently dislodges or shifts a lower denture.
  • Faster bone loss: The lower jawbone shrinks faster after tooth loss than the upper jaw, reducing the stable ridge needed to hold the plate.
  • Speech and eating challenges: It takes much longer to learn how to chew and speak clearly without the bottom teeth sliding around. Many people turn to options like Organ Mountain Dental for dental implants to lock the lower set in place.

What is the most common problem with dentures?

The most common problem with dentures is discomfort, pain, and soreness caused by an improper fit.

Common Issues with Dentures

  • Poor Fit and Slippage: As the jawbone and gum tissues naturally shrink over time, dentures lose their snug fit and begin to move or slip while eating and speaking.
  • Sores and Irritation: Ill-fitting or shifting dentures rub against the soft tissues of the mouth, creating painful friction sores, ulcers, and inflammation.
  • Denture Stomatitis: This frequent oral infection causes redness and swelling under the denture. It happens when fungi like Candida build up on unclean denture surfaces.
  • Difficulty Eating and Speaking: Adapting to artificial teeth often leads to trouble chewing hard or sticky foods and temporary speech changes or lisps.
