If Your Dentures Make Your Mouth Sore

Having dentures should not hurt. People who wear dentures may experience temporary oral irritation or soreness. Eating certain foods may cause temporary pain. For example, a seed or peanut may slip under a denture and cause irritation to the gum.

This type of irritation usually goes away after a few days once the source of trouble (in this case the seed or peanut) is removed. Often, it may be more comfortable to leave the denture out of the mouth during this healing.

Dentures are custom made specifically for your mouth; therefore, new dentures often require adjustments to areas that rest directly on the soft tissue. Sometimes, due to bony ledges and undercuts, dentures require alteration. To improve the balance and pressure of the denture during eating, the bite is sometimes adjusted.

Adjusting a denture requires a quick and simple dental visit. The denture dentist may use an indicator paste or marker on the irritated mouth tissue, which is then transferred to the denture upon placement, to determine the exact location on the denture that needs adjusting.

A rotary dental hand piece is used to contour the denture. Often, relief of an impinging denture improves comfort immediately; however, keeping the denture out of the mouth for a while may help the irritation or sore heal. After a few weeks, discomfort associated with a new denture often is eliminated and the denture functions without pain.

Over time, the mouth undergoes changes that can affect the fit of a denture. Since the bone and gum tissue of your mouth changes over time, it is important that denture wearers visit the denture dentist at least once a year for an oral examination, including an oral cancer examination.

A denture dentist can exam your mouth to determine the cause of your pain, evaluate your soreness and irritations, and adjust your denture. Depending upon the severity of the denture sore and the length of time the denture has not been in the mouth, it may be necessary to wear the denture the day before the dental visit so that the dentist can accurately resolve the problem. Often, a few denture adjustments will resolve discomfort associated with your denture.

Seeing a denture dentist can help improve the fit, function, and look of your denture, as well as detect any problems that are not related to the denture.

When Should a Denture Be Replaced?

There is no specifically agreed-upon chronological answer by dentists to "When should a denture be replaced?" There are instances where dentures have been replaced after 1 year or less, and on the opposite side of the spectrum, there are people who have worn the same dentures for 25 or more years. These ranges obviously are extremes.

However, on average, dentists seem to be replacing dentures somewhere between four to eight years. This would seem to imply that the average denture fabricated from contemporary biomaterials will wear out and deteriorate within that time and/or the average denture patient's jaws have changed so much that a new denture must be redone.

Each individual's denture needs are different. There are some factors that a licensed dentist takes into consideration when evaluating the need to replace dentures.

Denture Longevity Considerations

Lost vertical dimension:

The proper linear distance relationship between the upper and lower jaws is called vertical dimension. This is unique for each individual.

As one's jaw changes and the ridges upon which dentures rest shrink, a denture becomes loose and vertical dimension begins to change (the vertical dimension is said to be lost by a certain linear measurement unit such as millimeters). Additional plastic (acrylic resin) is added to the inside of a loosening denture (called relining a denture) to stabilize it by reducing looseness caused from jaw shrinkage. However, relining does not restore vertical dimension in an accurate way.

The current position held by most dentists is that when vertical dimension has been lost by three millimeters or more, a new denture should be fabricated in order to restore vertical dimension and maintain functional health.

There are individuals who have worn the same denture for extended periods with considerable loss of vertical dimension over time. Since vertical dimension loss is a slow, but nevertheless progressive, process, they have gradually adapted to a continually increasing closed bite position. These individuals often have a sunken facial appearance and usually appear much older than their chronological age.

Functioning with an abnormal vertical dimension may eventually result in alterations of the temporomandibular joints (TMJ, the jaw joint located in front of the ears). This can lead to significant pain and difficulty with effective eating and even the jaw motions involved with speech. It frequently becomes quite difficult, if not impossible, to restore such individual's proper vertical dimension and chewing efficiency by relining and repairing this older denture.

Tooth wear:

Aside from impaired ability to chew effectively, excess tooth wear will adversely affect esthetics and cause other problems associated with lost vertical dimension, as described above. While porcelain denture teeth will wear at a slower rate than plastic teeth, they nevertheless will wear and are more susceptible to chipping and cracking. Multiple cracked teeth will need to be replaced.

Deterioration: While the biomaterials used by dentists to fabricate dentures today are quite durable, they still deteriorate and exhibit dimensional change over time -- no longer fitting properly, even after relining.

Aging plastic looses its natural appearance and texture, and coloration fades, making dentures look quite artificial.

Deteriorating plastic also makes it easier for dentures to become excessively contaminated with microorganisms. This contributes to mouth irritation and bad taste, and socially unacceptable odors will develop that no amount of denture cleaning will seem to eliminate.

Keeping regular dental check-ups with your dentist so that one's dentures, soft tissues, and jawbone may be checked is essential to extending the life of a denture and maintaining oral health.
