What dental dentures are and how they replace missing teeth
Dental dentures are removable replacements for missing teeth made from acrylic resin, sometimes combined with metal. They sit on top of your gums and are held in place by suction, clasps, or dental implants. Dentures restore your ability to eat, speak clearly, and smile — functions that missing teeth make difficult or painful.
There are two main types. Complete dentures replace all your upper teeth, all your lower teeth, or both. Partial dentures fill gaps where you still have some of your own teeth. A partial denture clasps onto your remaining natural teeth to stay anchored.
Dentures are not permanent. You remove them to clean them, and you wear them during the day. Over time, your jawbone changes shape as it heals from tooth loss, so dentures need adjustments and eventually replacement to keep fitting well.
Key Takeaways
- Complete dentures replace all teeth on the upper or lower jaw; partial dentures fill gaps between remaining natural teeth.
- A dentist takes impressions and measurements of your mouth, then a lab fabricates the dentures over several weeks.
- New dentures require multiple adjustment visits to fit properly and feel comfortable when you bite and speak.
- Daily cleaning, proper storage in water or denture solution, and regular dental checkups keep dentures functional and hygienic.
- Dentures typically last five to seven years before the material wears down or your jaw shape changes enough to require replacement.
The process of getting dentures made and fitted
Your dentist begins by examining your mouth and taking X-rays to assess your remaining teeth and bone structure. If you need a complete denture, the dentist removes any remaining teeth (if not already gone) and allows the extraction sites to heal — usually four to eight weeks — before taking final impressions. This waiting period lets your gums settle into their final shape.
Once healing is complete, the dentist takes detailed impressions of your upper and lower jaw using a putty-like material. These impressions go to a dental lab, where technicians create a model of your mouth and fabricate the denture base and teeth. You may have one or two try-in appointments where the dentist checks the fit, bite, and appearance before the final denture is completed.
At your delivery appointment, the dentist inserts the finished dentures and makes adjustments so they sit evenly and your bite feels balanced. You will likely need follow-up visits over the next few weeks to fine-tune the fit as your mouth adjusts to the new dentures.
How to care for dentures daily and keep them clean
Remove your dentures after meals and rinse them under running water to wash away food debris. Use a soft denture brush or regular soft toothbrush with denture cleaner or mild soap — never use toothpaste, which is too abrasive. Brush all surfaces, including the side that touches your gums.
Soak your dentures overnight in a denture-cleaning solution, plain water, or a mix of water and white vinegar. This keeps them moist so they do not warp and gives the cleaning solution time to break down stains and bacteria. Never use hot water, which can damage the acrylic.
Clean your mouth even when you are not wearing dentures. Brush your remaining natural teeth (if you have any) and gently brush or wipe your gums, tongue, and the roof of your mouth with a soft cloth. This removes plaque and keeps your mouth healthy.
Common adjustments and repairs dentures may need
New dentures often need adjustments in the first weeks. Your dentist may grind small areas where the denture rubs or causes sore spots, or adjust your bite so your teeth meet evenly. These are normal and expected — do not try to adjust dentures yourself, as you can crack them or make the fit worse.
Over months and years, your jawbone shrinks as it heals from tooth loss. This is called resorption, and it happens to everyone. As your jaw shape changes, dentures become loose and may slip when you eat or speak. Your dentist can add material inside the denture (called a reline) to restore the fit without remaking the entire denture. A reline takes one to two weeks and costs less than a new denture.
Dentures can crack, chip, or break if dropped or sat on. Many dentists can repair a broken denture in a few days. If the damage is severe or the denture is very old, replacement may be more practical than repair.
Cost and how long dentures last
The cost of complete dentures varies widely depending on the materials used, the complexity of your case, and your location. Basic dentures cost less than premium dentures made with higher-quality materials or custom shading. Partial dentures usually cost less than complete dentures because they cover less area. Dental insurance may cover a portion of the cost if you have coverage that includes dentures; check your plan to learn what percentage is covered and whether there is a waiting period.
Dentures typically last five to seven years before the acrylic becomes stained, worn, or brittle, or before your jaw has changed enough that they no longer fit well. Some people get longer wear if they care for their dentures carefully and have regular adjustments. Relines and repairs can extend the life of dentures, but eventually replacement becomes necessary.
Eating and speaking with new dentures
Eating with dentures takes practice. Start with soft foods cut into small pieces — yogurt, scrambled eggs, mashed potatoes, soup, and cooked vegetables are good choices. Avoid hard, sticky, or very hot foods while you are learning. Chew slowly and use both sides of your mouth evenly to keep the denture stable. As you gain confidence, you can gradually add firmer foods.
Some people find that dentures affect their speech at first, especially sounds that require your tongue to touch the roof of your mouth or your teeth. Reading aloud and practicing speech helps your mouth adjust. Most people regain normal speech within a few weeks.
If your dentures slip or click when you eat or speak, tell your dentist. Slipping usually means the fit has loosened and a reline is needed. Your dentist may also suggest a denture adhesive — a cream or powder that creates extra suction — to improve stability while you are adjusting.
When dentures may not be the right choice
Dentures work well for many people, but they are not the only option for replacing missing teeth. Dental implants are surgically placed into your jawbone and feel and function like natural teeth, but they cost more and require surgery and bone density. Fixed bridges are cemented onto adjacent teeth and do not come out, but they require grinding down healthy teeth on either side of the gap.
Some people struggle with dentures because of a very small jaw, severe bone loss, or difficulty adapting to the sensation of wearing them. Others find that dentures slip too much despite adjustments, or that they cause persistent sore spots. If you are having ongoing problems, talk to your dentist about whether implants, bridges, or other options might work better for your situation.
Frequently Asked Questions
Do dentures feel natural?
Dentures feel different from natural teeth at first — most people notice the bulk of the denture base and the way it sits on their gums. Over weeks and months, your mouth adjusts and the sensation becomes less noticeable. Many people report that their dentures feel quite natural once they are used to them, though they will never feel exactly like natural teeth.
Can I sleep in my dentures?
Dentists usually recommend removing dentures at night to let your gums rest and to prevent bacterial growth. However, some people sleep in their dentures without problems. Ask your dentist what is best for your situation — if you do sleep in them, soak them in cleaning solution during the day to keep them hygienic.
What should I do if my dentures break?
Do not try to glue or repair dentures yourself — adhesives and home repairs can make the damage worse or create an unsafe fit. Contact your dentist right away. Many dental offices can repair a broken denture in a few days, or they can send it to a lab for repair if the damage is complex.
How often do I need to see my dentist if I wear dentures?
Visit your dentist at least once a year for a checkup, even if you wear complete dentures and have no natural teeth left. Your dentist checks the fit of your dentures, looks for signs of bone loss, and screens for oral cancer and other conditions. If you are having fit problems or sore spots, you may need more frequent visits.
Can I wear dentures part-time?
Yes, some people wear dentures only during the day and remove them at night. Part-time wear is fine, though your mouth may need time to adjust each time you put them in. If you wear dentures part-time, still clean them daily and store them properly to prevent warping and bacterial growth.
