Chipped or Cracked Tooth:

Your chipped tooth could be a dental emergency. A minor chip that causes no pain needs less care than a large chip that causes excruciating pain. A few factors, including how much pain you’re in, determine whether or not you need to get to the dentist immediately
Big chip or small chip, here’s what you need to do. First and most importantly is not to panic. To help prevent an infection you can rinse your mouth using warm, salt water. Apply pressure with a cloth or piece of gauze to stop bleeding. Use an ice pack to reduce swelling. Apply ice on your cheek or jaw. Don’t apply ice directly to your tooth and gum. Use dental cement (available at most pharmacies) to cover and protect the chipped tooth if you can’t get into see your dentist right away. Apply dental wax over the tooth to protect your mouth from any sharp edges. Take over-the-counter pain medication if you’re feeling pain. For large chips, try to save the piece that broke off. In some cases, it can be reattached through bonding.
When should you call your emergency dentist? If you’re feeling pain, experiencing swelling, or bleeding, call as soon as you can. The at-home remedies can help you until you can see your dentist, but don’t wait to make an appointment if you can get in sooner.
