I suffer from severe bad breath. I’ve been using different types of toothpastes but nothing seems to work. I have no major problems with my teeth such as sensitivity, decay or cavities. Please help. 

Bad breath or halitosis can cause considerable social embarrassment. Even though there are medical conditions such as sinus infections with post-nasal drip, diabetes or acid reflux that can cause bad breath, the most common cause is due to poor dental health, especially when you have a gum disease or periodontitis. You may need an oral exam by a dentist to rule out any disease.

The other warning signs of gum disease are bleeding when you brush or floss, swelling of the gums and itchiness or pain in the gums.

In case you have gum disease, it is important that you visit a dentist to get the condition diagnosed and treated before it can cause more damage to the gums and the supporting bone. Also, bad breath can occur if you have a dry mouth.

To avoid bad breath, make sure you brush your teeth and your tongue after eating. It is also very important that you floss at least once a day as gum disease most commonly starts between the teeth. You may use an antiseptic alcohol-free mouthwash.

You should visit a dentist at least twice a year for an oral exam or professional cleaning to prevent or treat any disease.

Make sure you drink adequate water (at least two litres) during the day to keep your mouth moist. You may also use sugarless chewing gum. Monitor the food and medications you take and check if any of them are causing bad breath. Avoid smoking and tobacco products and eating foods with strong odours.
