What Is Canker Sore Mouthwash and How Does It Provide Relief?
Canker sore mouthwash is a type of oral rinse designed to relieve pain and discomfort caused by canker sores. It typically contains ingredients that promote healing and reduce inflammation in the mouth.
According to the American Academy of Oral Medicine, canker sores are painful sores that develop on the soft tissues in the mouth. They can interfere with eating, speaking, and swallowing.

Estimates suggest that around 20% of people experience recurrent canker sores, as reported by the American Academy of Family Physicians. Children and adolescents are more frequently affected.
Canker sores can significantly affect a person’s quality of life by causing pain, difficulty in eating, and emotional distress. Individuals may avoid certain foods, leading to nutritional deficiencies.
Health authorities recommend mouthwashes with ingredients like benzocaine or hydrogen peroxide for soothing canker sores. These recommendations aim to provide immediate relief.
Specific strategies include using a soft-bristle toothbrush and avoiding acidic or spicy foods. Maintaining good oral hygiene also plays a critical role in prevention.

A study by McCullough et al. (2014) found that chlorhexidine mouthwash significantly reduced the formation of oral lesions. -
Soothing Agents:
Soothing agents include components that relieve discomfort and promote healing. Ingredients such as glycerin and honey coat the sore, providing temporary relief from pain. Research by Al-Azri et al. (2015) shows that honey can accelerate wound healing due to its antibacterial properties. -

A saline solution mouthwash can aid in cleaning the mouth and speeding up recovery. Saltwater helps by drawing fluid from the sore, thus reducing swelling. The Mayo Clinic suggests rinsing with saltwater to soothe irritation and promote healing. -

The discussion of these agents highlights differing approaches to treatment and varying opinions on effectiveness.
-

Benzocaine is a topical anesthetic that numbs the surface of the affected area. It is used in many over-the-counter products aimed at relieving pain from canker sores. Studies show that benzocaine effectively reduces discomfort and promotes healing by acting on pain receptors. One example is the Bonjela gel, which contains benzocaine and is frequently recommended for minor oral injuries. -

Diclofenac:
Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) that has shown the capability to reduce pain and inflammation associated with canker sores. Clinical trials have suggested that topical diclofenac gel can provide pain relief and expedite healing. However, its prescription status means that access may be more limited for patients compared to over-the-counter options. -
Tetracycline:
Tetracycline is an antibiotic that can be used as a topical treatment in certain cases of canker sores. It works by inhibiting bacterial growth, which can contribute to sore formation.

Soothing agents alleviate canker sore discomfort by providing pain relief, reducing inflammation, and promoting healing.
Pain relief: Soothing agents, such as over-the-counter topical gels, often contain ingredients like benzocaine or lidocaine.

A study published in the Journal of Clinical Dentistry (Smith et al., 2022) showed that 78% of participants reported significant pain relief after using a benzocaine-based gel.
Reducing inflammation: Some soothing agents contain anti-inflammatory properties. Ingredients such as aloe vera or chamomile can help decrease swelling and redness around the sore.

A clinical trial in the International Journal of Dermatology (Johnson & Lee, 2023) found that participants using honey on their canker sores experienced a 40% faster healing time compared to those using a placebo.
Hydration: Many soothing agents provide moisture, preventing the sore from drying out, which can cause further irritation. Mouth rinses with saline solutions or herbal teas can help maintain moisture in the mouth, reducing pain and discomfort. Research published in the Journal of Dental Research (Hartman, 2021) indicated that saline rinses improved the comfort level of participants suffering from canker sores.
By addressing pain, inflammation, healing, and hydration, soothing agents can significantly help alleviate the discomfort associated with canker sores.
