It is never normal for teeth to bleed during a filling. The only part of the tooth that can bleed is the nerve (pulp) if it’s unintentionally drilled into. Sometimes, your gums may experience light bleeding because of a rubber clamp pinching the tissue or if the drill comes into contact with the gums.

As dentists in Medicine Hat, our goal is to ensure that your teeth filling procedure is as smooth and comfortable as possible. Whether you’re scheduled for a filling, or you’re experiencing complications after a procedure, here is what you need to know about teeth filling, tooth sensitivity, and when to see your dentist.

What should I expect after a teeth filling procedure?

Fillings are a safe and effective way to treat cavities that involves a numbing agent injected around the decayed tooth and filling the space with new material. For a few hours after the procedure, your face may feel numb, tingly, or itchy, and you may experience difficulty eating, talking, and moving your face.

These feelings will go away once the numbing agent has worn off. However, if you’re experiencing any of the following symptoms, call your dentist as soon as possible:

  • Extreme pain or discomfort
  • Fever
  • Redness 
  • Excessive swelling

What does sensitivity after a filling feel like?

Sensitivity with the filled tooth and surrounding area is common. You’ll typically feel a sudden pain or uncomfortable sensation that is temporary and goes away as quickly as it comes. Some factors that can trigger tooth sensitivity include:

  • Cold food or drinks
  • Hot drinks
  • Acidic foods such as coffee, fruit, and juice
  • Biting down when eating 
  • Cold air hitting the tooth when breathing through the mouth 

How can I avoid having to get my tooth filled?

When it comes to cavities and fillings, prevention is key. Practicing consistent, daily oral hygiene helps fight cavities and build healthy teeth and gums. To minimize your chances of getting a cavity, we recommend:

  • Brushing twice a day or after every meal
  • Flossing regularly
  • Brush in circular motions with a soft-bristled toothbrush
  • Using toothpaste with fluoride
  • Eating a variety of healthy food
  • Limiting your intake of sugary snacks 
  • Seeing your dentist regularly for routine check-ups
