21 Home Remedies for Canker Sores

2.  Homemade Numbing Spray

You can create your own ‘numbing spray’ which will both ease the discomfort and also help to reduce swelling. Mix peppermint and eucalyptus oil and then put them into a glass mister bottle. You can then shake and spray directly onto the sore to relieve the discomfort.

This works to reduce inflammation as both these oils are anti-inflammatory, while both also have a minty fresh effect that will cool the area and numb it. Use as needed.

As an added bonus, using this homemade spray will also kill off bacteria and thereby reduce the likelihood of the sore becoming infected.
