It is important to know that seniors have different needs than younger people when it comes the teeth and mouth area because their bodies may change with age so there could be several issues which arise from doing these actions or simply being neglectful about them at all times . Some examples include lack of sleep leading up until bedtime where one has been continuously grinding his/her incisors throughout an entire workday without taking care, neatness habits going overboard by brushings too many times and many more!

-
Do not ignore early signs of oral issues.
If you notice any signs of mouth or gum disease, contact your dentist immediately. - Do not use alcohol-based mouthwash.
You thought that alcohol-based mouthwashes are an effective way of fighting off bacteria and bad breath, but they actually do more harm than good.
- Do not brush too hard.
Use the Wayne toothbrush which does not allow you to put excessive pressure on teeth. Brush at the gumline angling under the gum tissues.
- Do not leave your dentures in overnight.
It can lead to bone flattening and loose dentures.
- Do not neglect your tongue when brushing.
If you neglect to brush your tongue, bacteria and fungus may grow leading to possible infection and halitosis.
