Rinsing your mouth after dental crown: the short version
Rinse the same day, as normal. Neither a temporary crown nor a permanent one is affected by water, salt water, or mouthwash, and swishing cannot loosen the cement. If you have just had the preparation visit, a warm salt water rinse is often the most comfortable thing for the gum around the tooth, which has usually been pushed back and is sore.
What is actually going on
Crown cement fails from sideways pulling forces, sticky sweets, floss yanked upward, not from liquid moving past it. So the usual worry, that a temporary crown will be washed off, does not match how they come loose. Where rinsing earns its place is the gum. To capture the edge of the prepared tooth, the dentist typically packs a thin cord into the gum crevice, and afterward that collar of gum is tender, may bleed, and can look whitish or bruised. Warm salt water several times a day for the first few days eases it. With a permanent crown just cemented, you may notice a clove-like or chemical taste from the cement for a few hours, and rinsing helps. Occasionally a rinse dislodges a small hard flake, which is usually excess cement.
The first time, step by step
You can rinse the same day, and the only thing to wait for is a lip that seals. Try a small mouthful of lukewarm water over the sink first; if it runs out of the numb corner, give it another half hour. Once you can hold it in, swish normally. Expect the water to come out slightly pink if the gum was packed with cord, perhaps with a tiny hard flake. Notice how the tooth under a temporary reacts to the temperature and adjust the next glass. That evening, rinse again after brushing. Gum that still bleeds into the rinse after several days is worth showing your dentist.
Rinse Mouth After Dental Crown: What You Need to Know
Wait time
After a dental crown, you can typically resume rinsing your mouth same day.
Why
No special precautions
Tips for Rinsing your mouth After Dental Crown
- 01Use warm salt water after meals for two or three days if the gum around the prepared tooth is raw.
- 02If cold liquid makes a tooth under a temporary crown ache, rinse with lukewarm water until the final crown is on.
- 03A persistent bad taste or smell from around a crown is not something to rinse away; ask your dentist to check the fit and cement.
Common mistakes
- 01Swishing a strong mint mouthwash while still numb and swallowing some because the throat and tongue feel clumsy. It is unpleasant and avoidable; water does the job until sensation is back.
- 02Picking at a thread or gum tag that shows up after rinsing with tweezers or a pin. Anything still attached at the gum line is for the dentist to remove, and pulling can make the collar bleed again.
- 03Treating a daily rinse as a way around cleaning beside a temporary crown. Plaque left at its edge inflames the gum, and puffy, bleeding gum on fitting day makes it harder to cement the final crown cleanly.
