What is postoperative sensitivity?

Post-operative sensitivity in teeth after doing a composite restoration is caused by residual stress buildup due to polymerization shrinkage resulting in de-bonding of the restoration ensuing in an enamel crack; microleakage at the margins of the restoration and secondary caries results in postoperative sensitivity.

What are the possible causes of post-operative sensitivity?

The literature has theorized various causes of postoperative sensitivity, for example:

  • Polymerization shrinkage.
  • Marginal gaps.
  • Suboptimal adhesion.
  • Inadequate polymerization.
  • Unfavourable C-factor and residual dentin thickness.
  • Pre-existing tooth related factors, such as cracks.

Why are newly restored teeth sensitive for a period of time?

After the completion of a filling, teeth may be hot, cold, or pressure sensitive, which is completely normal and known as pulpitis. Anytime a tooth undergoes the trauma of being drilled and restored, the nerve can become agitated and produce sensitivity that can last for days to weeks.

What are desensitizing toothpaste?

1. Desensitizing toothpaste. Desensitizing toothpaste contains compounds that help to shield nerve endings from irritants. The most active ingredient is potassium nitrate, a compound that blocks pain signals traveling from a nerve in your tooth to your brain. After a few uses, your sensitivity will reduce.

Can teeth with fillings be sensitive?

Tooth sensitivity following placement of a filling is fairly common. A tooth may be sensitive to pressure, air, sweet foods, or temperature. Usually, the sensitivity resolves on its own within a few weeks. During this time, avoid those things that are causing the sensitivity.

Are teeth with fillings more sensitive?

Tooth sensitivity: A tooth that has just had a filling placed will be more sensitive to hot foods and cold foods, air temperature, and the pressure of biting. This type of tooth pain after filling a cavity should resolve within a few weeks.

How do I reduce sensitivity after a filling?

You can help to reduce sensitivity by:

  1. taking nonsteroidal anti-inflammatory drugs, such as ibuprofen (Advil, Motrin)
  2. temporarily avoiding hot or cold foods and drinks.
  3. temporarily avoiding acidic foods and drinks, such as citrus fruits, wine, and yogurt.
  4. gently brushing and flossing.
  5. using a desensitizing toothpaste.

Why are my teeth sensitive all of a sudden?

Many people experience sudden tooth sensitivity, or dentin hypersensitivity, from time to time. For most people who experience sudden tooth sensitivity, a common trigger is eating or drinking something cold, though hot foods and beverages can also cause an episode of tooth sensitivity.

What are the symptoms of pulpitis?

Symptoms of irreversible pulpitis include:

  • Intense pain.
  • Spontaneous pain.
  • Sensitivity to cold that lasts more than 30 seconds.
  • Sensitivity to heat.
  • Pain when the tooth is tapped.
  • Swelling around tooth and gums.
  • Fever.
  • Bad breath.

How does Sensodyne reduce sensitivity?

Sensodyne offers a range of toothpastes for sensitive teeth pain relief, with stannous fluoride or potassium nitrate as a desensitizing ingredient. Potassium nitrate soothes the nerves inside your teeth, preventing them from sending pain signals from sensitivity pain triggers such as a burst of cold air or hot coffee.

How long does it take for Sensodyne to work?

Clinical studies have shown that sensitivity toothpaste containing potassium nitrate, such as Sensodyne, relieve tooth sensitivity in as little as 2 weeks, with twice daily brushing.

What causes post-operative sensitivity in direct resin composite restorations?

There are various causes of post-operative sensitivity in direct resin composite restorations related to failures in diagnosis and indications for treatment and/or cavity preparation, the stages of hybridization of hard dental tissues, insertion of the material, and finishing and polishing the restoration.

What causes postoperative tooth sensitivity after dental treatment?

Introduction: The postoperative tooth sensitivity is a dental caries post-treatment complication of unknown origin. The variety of clinical symptoms of this condition, the contributing factors and their interactions may be presented by means of network analysis.

How can we prevent post-operative sensitivity?

To avoid or minimize the occurrence of post-operative sensitivity, it is imperative to make a good diagnosis and use the correct technique at all stages of the restorative procedure. Content may be subject to copyright. CEP: 57051-160, Farol, Maceió, Alagoas, Brazil.

How is postoperative sensitivity measured?

Postoperative sensitivity was measured at 24 h and 15 or 30 days after the restorative procedures using a visual analog scale (VAS). When present, information on the characteristics of the pain was also collected. The data were submitted to the McNemar test (α = 0.05).
