Dear friend.

Thanks for sharing your concern.

your symptoms are not directly related to usage of clindamycin.still if you want you can just speak to your dentist regarding an alternative antibiotic.

please check with your physician regarding your symptoms like nausea and vomiting.

once your canal preparation is completed,antibiotic has very less role then.

hope it helps.


take care.

hello there ,

According to your history i can suspect some remnant of the infected pulp tissue has left unexplored during the root canal procedure or there is a missed canal due to which the infection has gone worse and you have developed a periodontal abscess due to spread of infection to the underlying tissues.

This type of periodontal abscess drains in the oral cavity and may lead to nausea and vomiting.

once the abscess is drained the infected tooth needs to be explored again for root canal procedure.

you need to get an x ray done the affected area to confirm the presence of infection, approach a dentist for the treatment.

i hope this helps,

take care.

Hello and welcome to hcm,

Nausea and motion sickness may be due to-
Side effects of medicines taken.
Pus or abscess draining into the sinus causing such difficulties.
The root canal procedure has to be carried out perfectly with great care.
Get your medicines replaced after consulting with your dentist.
Take plenty of fluids as well as nutritious rich food.
Keep yourself nourished.
Also check whether your wisdom teeth are impacted or is it still erupting.
Hope this helps.

Thanks for asking the query,

Motion sickness, nausea and vomitting can be due to use of antibiotics, you can stop the use of antibiotic for sometime.

As you mentioned Re-infection of the root canal treated tooth has occured, i would suggest you to get clinical examination of the tooth, take an x-ray, depending upon which treatment will be decided.

Meanwhile you maintain a good oral hygiene, use lukewarm saline gargles 3-4 times a day.
Use antiseptic mouthwash gargles twice daily to prevent infection and promote healing.

Hope this helps out.

59 year old white female, 5ft 2in, 145lbs... good general medical condition.8 months ago I had a rood canal of an upper molar... the next day I suffered a severe Bells Palsy of the facial nerve on the same side, which has not fully recovered. I now need another root canal on the same tooth, but am terrified of the procedure as I am not sure if the Palsy is related to the original root canal. Should I be concerned?

I had a root canal done last Thursday on the last upper left molar. Within the hour, my left cheek swelled up and I had minor pain. The swelling has gone down a bit but still sore and I noticed a small lump on left cheek...this has never happened to me (I had a previous root canal on another molar). Should I contact the endodontist that did the procedure or my dentist? Could this be an infection? I have no fever and only the discomfort of the root canal/cheek

It has grown bigger and now hurts quite a bit and it is causing my front left tooth and gums to hurt. It also hurts if i press down on the bottom of my left nostril as if it were bruised.

I have had a small red sore on my gum in the middle going toward the back of my mouth on the right side on and off now since July. I have used the Orajel antiseptic healing rinse. It went away. I stopped using the rinse and it came back. I began brushing my teeth more and flossing regularly and it went away again. I did fall short of my oral hygeine practices and it came back. I went to the dentist. He did X-rays for other pain I was having on the other side of my mouth (upper). I showed him the sore and he said it did not look serious and prescribed me some amoxicillin for possible infection. He told me to brush the area really good and floss. I started to brush really well again and floss and it went away. I did not take the antibiotics right away. Well now it has come back and I am taking the antibiotics, although I took half the bottle and stopped and now I am taking the rest, so it may not be effective. Ultimately, I am seeking professional advice. Does this sound like something serious? If not what is your conclusion?
