Hi Sydney,
I have never heard of this particular reaction from liquid chloral hydrate. What are in the injections that you are getting weekly and are they being administered by a physician or dentist?

A suggestion would be to google <xylitol oral products>. Xylitol actually helps prevent tooth decay and can be very soothing and healing on the oral tissue. The powder comes unflavored and it can be used as an oral rinse and/or on a soft bristle toothbrush. The other products come in peppermint, spearmint, cinnamin and fruit flavors.

Another suggestion is to stay away from products that contain sodium laurel sulfate as this is actually a poison and it is found is most commercial toothpastes, shampoos and soaps.

Perhaps some immune boosting supplements would be helpful? Like buffered vitamin C, B complex, zinc, probiotics, and a multi vitamin that is meant to be taken twice a day. Pure aloe vera juice is excellent for healing oral tissue and also stimulates the immune system response.

Sending you lots of well wishes!
Bryanna
