Practicing good oral hygiene is important if you want to have a winning smile. But it's also essential for you to prevent tooth decay, gum disease, tooth loss, and infections that can lead to more serious health issues like Ludwig's angina. Ludwig's angina is a rare but potentially deadly bacterial infection that usually affects your molars, spreads to the floor of your mouth and your neck, and can close off your airway. If you think you may have Ludwig's angina, you should have it diagnosed and treated by your medical professional immediately. If you're not showing symptoms of Ludwig's angina, you can rest assured that by practicing good oral hygiene and seeing your dental professional for regular visits, you can keep your mouth healthy and infection-free so you can continue smiling.
