Dementia - A Carer's Guide to Oral Health

A diagnosis of dementia is a truly traumatic time for everyone involved.  Partners and family members find themselves in a position where they become carers to their loved one, feeling a huge amount of fear and uncertainty about what the future holds.  The simplest of daily tasks can become overwhelming.

While we can't help you overcome every hurdle, we can provide advice and support on helping someone with dementia maintain their oral health, such as tooth brushing and dietary advice, denture care where necessary and recognising when someone may be in pain or discomfort caused by toothache.

Daily care

Establishing a daily routine is of real benefit, particularly in the early stages of dementia.  Encourage the person to care for their own teeth for as long as possible.  As a carer you can help by reminding them when to brush, and show them how to apply toothpaste to the brush if necessary.  It might be worth considering an electric toothbrush as they may be easier to handle and can brush their teeth more effectively.

As dementia progresses the person may forget why they need to brush their teeth or lose the ability to do it, so the carer may need to take over the task.  The easiest way to do this is have the person sit in a chair, and stand behind them, similar to the way a dentist treats a patient. 

Your dentist or hygienist can provide guidance and tips on the best methods for you.

Signs of a problem

Some people, especially those in the later stages of dementia may be unable to explain pain or discomfort they may be experiencing in their mouth.  However, changes in their behaviour can give you an indication that something is not quite right.  these include:-

  • refusing food
  • frequent pulling at their face or mouth
  • increased restlessness, moaning or shouting
  • disturbed sleep
  • refusing to wear dentures (if normally worn)

If you suspect the person you care for has toothache, contact their dentist for an emergency appointment.  They can help arrange home visits if necessary.

We can help

We can provide you with support and advice on lots of oral issues that can arise in people with dementia, such as difficulty wearing dentures, dry mouth due to medication and helping individuals manage dental treatment.  

Good oral health is not simply about keeping your mouth in good shape, it can mean a world of difference to overall wellbeing, especially in those with dementia.

4 signs you might be grinding your teeth at night

I have been a life-long tooth grinder.  As a child my parents could hear my nocturnal gnashing from their bedroom and it continued into adulthood. 
However, despite my line of work, I only recently had a splint made to wear at night and I've noticed a huge improvement. I knew all the symptoms and issues that can arise from tooth grinding, but seemed to just accept it as a part of my life.
But no more!
So I've put together a list of signs to watch out for, so that you don't do what I did.  While the following symptoms are common in those of us who grind our teeth, they may be the result of a different ailment, so always get any issues you have checked out.
1. Headaches
Headaches can be a common symptom of grinding or clenching, particularly when you experience them first thing in the morning and the pain is located around your temples and/or ears.
2. Jaw pain or tenderness
The average human bite produces 70 lbs of pressure when chewing food.  If you grind or clench while you…

Dental Implants

IF YOU’RE suffering with loose teeth or irritating dentures, you may feel like you have no option but to ‘put up with things’. Fortunately, there is a modern solution – dental implants. A natural-looking and stable replacement, implants are securely connected to your mouth; just like real teeth.

Many people choose implants because they dislike the discomfort and stigma associated
with dentures, or are looking for an alternative to bridges. Dental implants look and feel just like ‘normal’ teeth, giving you the freedom to enjoy the foods you love in complete confidence.

Teeth In A Day
‘Teeth in a Day’ is a type of implant treatment, which has been streamlined to deliver a stable set of
teeth in just one day; it works by placing dental implants as a secure anchor in the jaw, and can be used to replace one or more missing teeth, up to a full set. The ‘Teeth in a Day’ implant method means less dental appointments and less time spent in the chair. There’s no need to wait for your new smil…
