Yeah, that's a good idea... Aquamarine, Lapis Lazuli, Amber, Jet, Malachite are crystals that relieve toothaches. Calcite is also known to be used for bone deficiencies...
You may also wanna boil a 2-inch bark of a margosa tree with 5-6 cloves and in one cup of water. Once it boils, strain the liquid and store in the refrigerator. You can apply this concotion of affected tooth to relieve pain.
If that's too much effort just use clove oil or put a garlic clove on affected area to relieve pain.
However, please consult your physician and dentist before using the above, just in case you're allergic to any of the ingredients.
Hope you feel better
