Tooth and Mouth Problems

Dear sir/mam, I'm a lactating mother,can i take homeopathy medicine plantago major, it is good for me as well as for my baby

I have decayed tooth. I consulted online via Practo. The doctor said the tooth is decayed and you might have to do a Root Canal. I would like to the cost of Root Canal in Mumbai.

Noticed this in the teeth of my 3y 10m old son. He absolutely resents brushing, but I somehow manage to do it 2 times daily... But this got me worried... What should I do?

I have got some kind of wound inside my mouth cheeck from last 3-4 days which seems small bulge with might be pus like swelling (light white colour) and cut with small dots marks. It pains a lot and causing discomfort while eating and opening mouth. Picture attached with wound mentioned to locate the area. Also my gums has swollen and seems like coming over last few teeth. Can you suggest what could be reason and how I can get some relief from it. I have taken becosules tab from yesterday evening but not much improvement. Since my city has lockdown till month end can't visit any dentist as well as they are not seeing in opd.

I am having third molar on the left side of my mouth and I also have swollen lymph nodes. I took blood test and my hS-CRP was 55 . Is it possible?

He has Unbearable pain since many hours despite taking imol painkiller twice,any home remedy or relief?

I have developed red patches on roof of my mouth. Although, it's painless and non itchy. I have no difficulties in swallowing food as well. But, I had history of smoking for four years. I have already quit it from 1.5 months. I was also  Gargling my mouth with hot water for few days. Have the patches formed due to thermal burn? But, as I told it's painless with no such burning sensation and neither do I have any such patches or lesions at any other parts of mouth.

Please suggest a good water flosser for deep cleaning gums at a reasonable price. Do oracura and waterpik offer the same products?

I removed my upper right wisdom tooth 20 days back. I went for follow up and site is healed. I have lower jaw pain, ear pain and neck pain for 2 months. OMFS said this extraction will help and I did that. That doesn't help the symptoms. Have bad neck pain, ear pain and lower jaw pain with swelling. I have post nasal drip and nose congestion for more than a month. I was using antihistamine tablet and Flonase spray before extraction. Not using it after the extraction. When can we use the nasal spray after the wisdom tooth removal? Is it ok to use on tht nose? Or do we need to wait till the site is healed and gums formed?

Sudden pain in gums and teeth. Please suggest any home remedies to cure it. It might be due to swelling but cant figure it out.
