Hello, bleeding gums could be because of deposits on teeth surface or food lodged in between teeth. Visit a dentist and get your scaling and polishing done. Brush your teeth twice daily, night brushing is very important. Floss regularly. Rinse after every meal. Visit dentist every 6 months.

Generally you need to have a meticulous oral hygiene after the crowns/caps were placed. If you have not followed up with your dentist, now is the time to do it.

The best bleeding gums treatment is to remove from your teeth the plaque bacteria that causes gum disease. When dental plaque builds up, it turns into tartar, a hard, sticky substance that adheres to your teeth. Without regular teeth cleanings, dental tartar can become a breeding ground for even more plaque, which can creep below the gum line and lead to an infection that causes bleeding gums.So if you notice that you have bleeding gums, see a dentist as soon as you can. Seeking bleeding gums treatment at the first sign of a problem can help reverse gingivitis and help prevent periodontal disease. Other treatment options, such as scaling and root planing procedures, slow down the process of gum disease. If you suffer from an advanced form of periodontal disease, your dentist may recommend ongoing bleeding gums treatment or periodontal therapy. In some cases, dental surgery may be needed to control the bleeding
