1. Bleeding gums
Bleeding gums after brushing or flossing is a tell-tale sign of gum disease. The build-up of plaque at the base of the tooth that causes them to become red or swollen can also lead to bleeding.
An improved brushing routine and a more dedicated floss can often sort this out, but it may be best to visit the dentist to check whether the disease has developed and is on its way to more serious complications.
2. A metallic taste in your mouth
You know the bleeding gums we talked about earlier? Well, not all the blood made it to the sink after you finished brushing your teeth, and it is that blood that could be causing the metallic taste in your mouth.
3. Bad breath
According to the NHS, around one in four people have bad breath on a regular basis. Not only is halitosis, to give it its scientific name, an unpleasant condition (especially for people around you),
it could also be a sign of gum disease.
Poor oral hygiene is often to blame, with any food trapped on your teeth (particularly between them) causing a build-up of bacteria in the mouth. These bacteria produce toxins and foul-smelling gasses that could lead to persistent bad breath and gum disease
