Remedy for tooth ache

no, homeopathy is to complex for that. Tooth ache from sweets is genrerally amonium carb, natrum carb, phosphorous or sepia. You have to check those against other indications of those remedys in light of the person's other symptoms and emotional pains. so look those up online and see if you identify with the emotionals of any of those. 

Hi Ernst 

Does taking raw ginger/garlic regularly for few days suffice to kill less moderate tooth cavity infection on its own? Guessing that could be a better option than to get the cavity drilled and filled and taking lot of antibiotics?

Thank you 

It can kill the bacteria that have shown up, but the issue is somethign deeper. Most common issue is lack of sunlight which means lack of Vitamin D. almost everyone is d deficient, so get a good source of vit D.
