Your teeth expand and contract in reaction to changes in temperature. Hot and cold food and beverages can cause pain or irritation to people with sensitive teeth. Over time, tooth enamel can be worn down, gums may recede or teeth may develop microscopic cracks, exposing the interior of the tooth and irritating nerve ends. Just breathing cold air can be painful for those with extremely sensitive teeth.
Gum or periodontal disease can cause inflammation, tooth loss and bone damage. Gum disease begins with a sticky film of bacteria called plaque along the gum line. Gums in the early stage of disease, or gingivitis, can bleed easily and become red and swollen. As the disease progresses, teeth may fall out or need to be removed by a dentist. Gum disease is highly preventable and can usually be avoided by daily brushing and flossing. One indicator of gum disease is consistent bad breath or a bad taste in the mouth.
Bad Breath (Halitosis)
Daily brushing and flossing helps to prevent the buildup of food particles, plaque and bacteria in your mouth. Food particles left in the mouth deteriorate and cause bad breath. While certain foods, such as garlic or anchovies, may create temporary bad breath, consistent bad breath may be a sign of gum disease or another dental problem.
Canker sores (aphthous ulcers) are small sores inside the mouth that often recur. The duration of canker sores generally lasts one to two weeks and can be reduced the use of antimicrobial mouthwashes or topical agents. Canker sores have a white or gray base surrounded by a red border. Foods such as orange juice, lemon juice that are acidic, or hot and spice foods should be avoided not to aggravate the sore and cause more pain.
