Dentures for Older Adults
Dentures for Older Adults. Many older adults suffer from poor dentition, and dental care is a major geriatric concern. Tooth loss can be caused by periodontal disease, tooth decay, and trauma. Other contributing factors can include drug and tobacco abuse, poor access to dental services, lack of knowledge about proper dental care, and lack of financial resources.
|TIPS ABOUT DENTURE CARE |
Edentulism is defined as the loss of all permanent teeth. It is an irreversible condition that is the final stage of poor oral health. Edentulism is an important topic in geriatric care because not only does it usually reflect poor oral health, but it can also have a significant influence on overall health, nutrition, verbal communication, and self-confidence.
Edentulism is common. CDC data indicate that about one-quarter of adults over age 60 have no natural teeth. Dentures are one option that patients have for dealing with tooth loss. Dentures are not only important for aesthetic purposes but also for mastication (chewing), speech, oral maxillofacial structure, and nutrition.
Dentures for Older Adults
There are two types of dentures – complete and partial. Complete dentures can be “conventional” or “immediate.”
Conventional complete dentures are made and fitted after teeth have been removed and the alveolar tissue has had time to heal. This process can take between 8-12 weeks and many patients find it unappealing to wait that long.
Immediate complete dentures are made in advance and can be placed as soon as the teeth are removed. Although this option is cosmetically appealing, it is only a temporary solution. After tooth removal, the bone and gingival structure change drastically and multiple adjustments need to be made to accommodate those structural changes.
Partial dentures are used when one or more teeth remain in the jaw. Therefore, not all teeth need to be replaced. Partial dentures can be fixed or removable. Fixed partial dentures, also known as a bridge, are used when replacement teeth are cemented to neighboring teeth.
Removable (flexible) partial dentures are typically more affordable and consist of a prosthesis that can be removed and reinserted by the patient. Partial dentures fill the space in between missing teeth, helping to prevent other teeth from changing position. Because they are removable, they can be easily cleaned.
Alternatives to Dentures
Dental implants are an alternative to dentures. Implants are artificial teeth that are surgically anchored into bone and are not removable. In addition to being able to replace individual teeth, implants may also be used in conjunction with dentures, offering better retention, support, and bone maintenance than traditional prostheses. Not all patients are good candidates for implants and many cannot afford their high cost. Patients who are heavy smokers, use bisphosphonates, have poorly controlled diabetes, or have poor bone availability are less-ideal candidates for implants.
A set of upper and lower complete dentures typically costs $2,000-$4,000. Partial dentures are around $1,000-$2,500 per arch. Denture prices can vary, however, depending on case complexity as well as tooth and material selection. A single tooth implant costs, on average, $3,000-$4,000. Additional diagnostic, imaging and surgical fees may also apply, depending on the case.
Daily Care and Handling
Dentures should be rinsed with running water after every meal to remove loose food debris. Patients should brush them daily with a soft-bristled toothbrush designed for cleaning dentures. Patients should also perform routine oral care after removing the dentures. This involves cleaning the gums, natural teeth, tongue, and palate with a soft-bristled toothbrush or gauze.
Patients should also receive instructions from their dentist about proper care and handling of dentures. Some general rules are that dentures should be handled carefully because attachment points and clasps can break during cleaning. Another important recommendation is to place a towel below the dentures during cleaning so that dentures won’t break if inadvertently dropped onto a hard surface.
Dentures should be kept in a moist environment when not being worn. They should be soaked overnight, preferably in a denture cleansing solution. Studies indicate soaking dentures overnight in alkaline peroxide-based cleansing solution or water reduces Candida and bacteria levels on the denture surface in comparison to dry storage.
Things to Avoid
Patients should avoid using hard-bristled toothbrushes, toothpaste, household cleaners, or bleach for denture cleaning as they may damage dentures. Hot water can warp dentures and should also be avoided.
Some of the most common complications of dentures include traumatic ulcers, gingival hyperplasia, denture stomatitis, loss of denture retention, denture breakage, and trouble chewing or speaking due to abnormal fit. The table below reviews the most frequent complications and how to troubleshoot them for your patients.
Routine Follow Up
Ongoing follow-up with the same dental provider who made the denture is strongly recommended. Over the long term, patients should visit a dentist every 6 months to assess fitness and assure that dentures are receiving proper care. Poor-fitting dentures can lead to bone loss over time, resulting in a still worse fit and often making the dentures unusable. Dentures will require adjustments due to normal wear and changes in weight, but complete dentures should last 5-7 years before replacement is necessary.
|Table 1. Complications and Management of Dentures|
Small, painful mucosal lesions that most commonly develop in the first days after insertion of a new denture
|Ill-fitting dentures with overextended flanges, unbalanced occlusion or small excess of material, friction points at the frenulum or muscular attachments of the mouth.||Painful mucosal ulcerations have a yellowish floor and red margins, with no hardening or thickening of oral tissues. The irregularly shaped lesions are usually localized to the buccal and lingual sulcus.||Squamous cell carcinoma, bacterial, fungal and viral diseases, and other oral mucosal diseases.||Denture removal. Ulcers usually heal in about a week. For symptomatic relief, recommend benzamine hydrochloride 0.15% mouthwash or spray. Use chlorhexidine gluconate 0.2% mouthwash for oral rinses and soak the dentures overnight to prevent and treat infection. Patients should see a dentist if ulcers reoccur, or last longer than a week, so that dentures can be adjusted to relieve pressure.|
Enlargement of the oral mucosa
|Reaction to low-grade continuous chronic trauma induced by denture flanges, which have thin, sharp edges.||Reactive mucosal enlargement.||Fibrous hyperplasia vs inflammatory papillary hyperplasia.||Patients should see their dental provider for adjustments to their dentures. The hyperplasia resolves almost entirely after removal of the cause. Sometimes minor surgery is required.|
Chronic infectious inflammatory disease of the oral mucosa directly contacting dentures
|Infections with Candida, Staphylococcus, Streptococcus and sometimes irritation from medications.||Asymptomatic inflammatory lesions, with erythema and edema (without plaques) that are found in the denture-bearing area, more frequently in the maxillary surface.||Squamous cell carcinoma, traumatic ulcers.||Adopting strict methods for oral and denture hygiene, with removal of the denture overnight and soaking it in an antiseptic solution. Patients should see a dental provider if it persists.|
