An oral ulcer is a painful sore that develops on the lining of the mouth, such as the lips, cheeks, tongue, gums, or floor of the mouth. It usually appears as a round or oval lesion with a white or yellow center and a red, inflamed border. Oral ulcers can cause discomfort while eating, drinking, or speaking. Common causes include minor injury, stress, nutritional deficiencies, hormonal changes, infections, or systemic conditions. Some ulcers heal on their own within one to two weeks, while others may persist longer. Poor oral hygiene and weakened immunity can worsen the condition. Treatment focuses on relieving pain, reducing inflammation, and addressing the underlying cause. Maintaining good oral hygiene and avoiding irritants help promote healing. dental clinic in Nolambur, dentist in Nolambur, best dental clinic in Nolambur, best dentist in Nolambur, root canal treatment in Nolambur, dental crowns and bridges in Nolambur, wisdom tooth removal in Nolambur, dental brackets and wires in Nolambur, denture treatment in Nolambur, near me, dental clinic in Mogappair, dentist in Mogappair, best dental clinic in Mogappair, best dentist in Mogappair, root canal treatment in Mogappair, dental crowns and bridges in Mogappair, wisdom tooth removal in Mogappair, dental brackets and wires in Mogappair, denture treatment in Mogappair, near me.
