I had a crown placed in October, and my mouth hasn’t felt right since. The tooth was very sensitive with the temporary crown, and after the permanent crown was cemented, new symptoms started. I’ve been experiencing increased saliva, chapped lips, sores at the corners of my mouth, a bitter taste, and ongoing bad breath. Eating sugar or gluten seems to flare up the symptoms. I’m concerned that the dental work may have led to a yeast infection that hasn’t gone away. Could that be happening? – Joshua from MN

Joshua,

You’re describing several issues that may relate to your dental visit, but they likely have different explanations.

Stress commonly triggers sores at the corners of the mouth and oral yeast infections. In contrast, bad breath combined with a bitter taste typically points to plaque buildup.

Is Crown Sensitivity Normal?

Teeth with temporary crowns often feel more sensitive. That sensitivity can linger even after the final crown is placed. In most cases, time allows the nerve to settle. If pain intensifies or becomes severe, your dentist should reassess it.

What Practical Steps Can You Take Now?

Soreness can make you hesitant to brush and floss thoroughly. However, easing up on hygiene can worsen breath and taste issues.

To improve your symptoms, focus on consistent care:

• Brush carefully after every meal.
• Floss at least once daily.
• Do not avoid the sore areas—clean them gently but thoroughly.

This should reduce the bad breath and bitter taste.

If the yeast infection continues, ask your provider about Nystatin. It is commonly used and usually resolves the infection effectively.
