As dementia progresses, the person with dementia may forget how to brush his or her teeth or forget why it is important. As a caregiver, you may have to assist or take a more hands-on approach.
Persons with Dementia are susceptible to dental problems because of:
Saliva is essential to maintain a healthy mouth and to prevent the onset of dental decay and other oral lesions. Saliva acts as a lubricant and also cleans the mouth and teeth. Lack of saliva can thus lead to a build-up of plaque and increase the risk of dental decay, gum disease and infection. A dry mouth can also cause dentures to become loose and uncomfortable. A moisturising mouthwash may help with dry mouths as well.
Certain medications can cause involuntary repetitive movements of the jaw and tongue, making it difficult to wear dentures and may cause wearing down of teeth. In some cases, these movements will continue after the drug is stopped. A dentist may be able to advise on what can help, and how best to ensure that your loved one is comfortable.
Reduced Oral Care
Physical limitations may affect abilities to maintain their oral health.
What to Look Out For?
Behaviours that may suggest your loved ones are experiencing dental problems include:
•Refusing to wear dentures
•Facial expressions such as grimacing
•Increased restlessness, agitation, shouting
Tips On Toothbrushing For Persons With Dementia
1. Mild Dementia Stage
Your loved one may find it easier to use an electric toothbrush or a toothbrush with an adapted handle to improve their grip.
2. Moderate To Severe Stage
•Change to an electric toothbrush or a toothbrush with larger handle to improve grip
You can modify the toothbrush handle by putting the handle through a tennis ball. Try different types of toothbrushes until you find the best choice
•Give short and simple instructions
Break down instructions step by step. E.g. "Hold your toothbrush." "Put toothpaste on the brush." Then, "Brush your teeth."
•Use a ”watch me” technique and show your loved ones how to brush their teeth
•Put your hand over your loved ones’ hand to guide them in brushing
Give your loved one the toothbrush with toothpaste already on it and put your hand over theirs to start the up and down brushing movement to help get started. It may be easier to stand behind your loved one while doing this.
•Postpone brushing to a later time if your loved one is not cooperative.
Anti-plaque mouth wash can be helpful in preventing gum disease—but ONLY if it won't be swallowed.
My Loved One With Dementia May Swallow Toothpaste Or Mounthwash, What Can I Do?
Safer options for persons with moderate to severe dementia include:
1. Fluoride free toothpastes
2. Alcohol-free, chlorhexidine gel to clean teeth
Use your fingertip or a very soft toothbrush to apply the gel to the teeth
3. Any commercial alcohol-free chlorhexidine mouthwash
•do not gargle mouthwash
•instead, dip toothbrush in mouthwash, shake off excess and brush teeth
4. Sodium bicarbonate solution
mix 1/2 teaspoon of sodium bicarbonate in 200mL of water, dip toothbrush in mixture, shake off excess and brush teeth
5. Brush teeth with toothbrush and water only
mechanical brushing is more important than the pastes/mouthwash we use
