As your doctor, Id recommend a few additional steps your husband can take to manage dry mouth, especially since water alone isnt helping

Use saliva substitutes like Biotène gel, mouthwash, or sprays, which help keep the mouth moist.

Chew sugarfree gum or suck on sugarfree lozenges xylitolbased is ideal to stimulate natural saliva flow.

Avoid alcoholbased mouthwashes, caffeine, tobacco, and salty or spicy foods, which can worsen dryness.

Run a humidifier at night to keep the air moist.

Since he has mouth sores, a saltwater rinse or a nonalcoholic antiseptic rinse can help heal them.

If symptoms continue, it may be related to his thyroid meds or an underlying issue, so a review with his healthcare provider would be important.

Hello, He could try a mouthwash designed for dry mouth. Have a great day!

Rinse mouth with warm salt water, use topical orabase ointment on soars or gentian violet paint, Tylenol for pain.

I recommend Biotene, all day dry mouth spray, or act dry mouth lozenges. There are prescriptions available but I do not recommend this. As for the sores he should probably visit his dentist for further evaluation.

He needs to go visit a dentist and have the dentist check his gums teeth and the inside of his mouth. If he does not do that it will not get any better. There are a number of things that can cause this and to go to the dentist is the best way.

Some medications can cause dry mouth as a side effect, read the medication insert to see that possibility

Thyroid meds can help contribute to dry mouth syndrome. Sugarless sucking candies will help encourage saliva flow. Products like Biotene rinse and toothpaste will also help.
