You may notice blood on your toothbrush or streaks of blood in the toothpaste you spit out whilst brushing your teeth, as well as blood on the food you bite into or a metallic taste in your mouth – these are all signs of gum inflammation; if they do not go away or occur frequently, you need to see a periodontist.
Bleeding caused by minor gum trauma usually stops within a few hours. If, following the fitting of braces, crowns, bridges or veneers, the gums around them are bleeding, swollen or inflamed, or if the wound continues to bleed for more than an hour after a tooth extraction, you should seek immediate medical attention.
It is important to understand that minor gum injuries are nothing to worry about and will heal within 2–3 days. However, if you have seriously injured your gums—and possibly a tooth—for example by falling or hitting your jaw, you must seek medical attention immediately.
A metallic taste of blood in the mouth may be caused by gum inflammation; in such cases, a periodontist can help treat the condition. A metallic taste of blood in the mouth may also be caused by certain medications, pregnancy or even cancer, so it is essential to consult a specialist.
