After getting a temporary crown in January, my teeth felt sensitive. My dentist placed the permanent crown in mid-February, and the sensitivity continues. I also have chapped lips, bad breath, bitter taste, extra saliva, and sores in the corners of my mouth. Could a new crown cause all the symptoms I’ve described? I’m concerned about what’s causing it. – Thanks. Jameson from VA
Jameson,
We understand your concerns about experiencing multiple symptoms. An accurate diagnosis requires more information and a clinical examination. However, we can offer some insight based on your description.
The symptoms you’re describing, such as sores in the corners of your mouth and an oral yeast infection, can sometimes be associated with periods of stress. Stress can affect the body’s immune response, making you more susceptible to infection.
Bad breath can stem from various sources. However, improving your oral hygiene routine may improve bad breath and a bitter taste.
It’s also worth noting the following:
- Temporary Crown Sensitivity: It’s not uncommon for a tooth with a temporary crown to have heightened sensitivity. This sensitivity can continue after a dentist places the permanent crown.
- Burning Mouth Syndrome: Following a particularly stressful dental procedure, some individuals may develop a condition known as burning mouth syndrome. A key characteristic of this syndrome is often a dry mouth. Since you’ve mentioned increased saliva, this syndrome seems less likely to be the cause in your situation.
How Can You Manage Your Symptoms?

Here’s some advice that may help improve the bad breath and bitter taste, and potentially alleviate some of your other concerns:
- Diligent Oral Hygiene: Despite any soreness, it’s advisable to be extra thorough with your oral hygiene. This includes brushing carefully after every meal.
- Regular Flossing: At least once daily, floss to remove food particles and plaque between your teeth and under the gumline.
- Yeast Infection Treatment: If the oral yeast infection doesn’t improve with your increased hygiene routine, a healthcare professional can prescribe an antifungal medication, such as Nystatin, to treat it effectively.
Discuss your symptoms with your dentist if they persist.
