if you are looking for the cheapest way than you should go to a dental school where you will be treated by dental students under the supervision of experts. There the treatment is at very low cost or may be free depending upon the financial condition.

Now to get rid of immediate pain you can do warm saline gargles, do listerine mouthwash and then put toothpaste into the chipped tooth, relax for 10 minutes. This will help in getting rid of pain.
