Canker sores can be caused by a variety of factors, including stress, hormonal changes, food sensitivities, and certain nutritional deficiencies. They can also be triggered by minor injuries to the mouth, such as biting the inside of the cheek or brushing too hard. Additionally, some people may be more prone to developing canker sores due to genetic factors or underlying health conditions. **

Without being able to see the sores, it is difficult to definitively say whether they are canker sores. Canker sores are small, shallow ulcers that appear inside the mouth and are typically white or yellow with a red border. They can be painful and may make eating and talking uncomfortable.

Canker sores are typically treated with over-the-counter topical medications such as numbing agents or corticosteroids to help reduce pain and inflammation.

They can provide recommendations for managing and treating canker sores, as well as identify any underlying dental issues that may be contributing to the development of canker sores. If the canker sores are persistent or severe, it is advisable to seek professional medical advice from a healthcare provider. **

They are not contagious and can be triggered by factors such as stress, hormonal changes, or certain foods. It's important to differentiate between the two as treatment and management may differ. **
