Detailed Answer:
Hello,
Thank You for trusting HealthcareMagic,

Canker sores are different from cold sores. Cold sores occur outside mouth around lips and is caused by viral infection while canker sores occur inside the mouth and are not contagious.

Canker sores are small sores in the mouth and tongue, appear white and surrounded by area of redness. Canker sores can be triggered by use of antibiotics.

Canker sores will heal without any treatment.

There are few things you can try to help relieve pain and faster healing:

-Avoid citrus fruits, juices. and carbonated sodas
-Avoid sugary gums, Lozenges etc
-Continue Peroxide rinse.You can also rinse mouth with over the counter antiseptic mouth wash.
-Include probiotic rich food like yogurt in diet
-Use over the counter anesthetic gels like Orajel for pain


You do not need to discontinue the antibiotic at this point. However, if the sores and pain are worsening, you develop painful swollen lymph nodes or the cold sores are not going away in next 10 days, consult your primary care provider/ dentist.
