Tooth Sensitivity after Filling
Experiencing tooth sensitivity after a filling is relatively common, but it can still be concerning. Whether it’s a temporary sensation or something that persists, understanding the reasons behind tooth sensitivity after a filling can help you manage the discomfort and know when to seek further care. If you have recently had a tooth filling installed or are preparing for one, read on to learn more about why tooth sensitivity might occur, what you can do to alleviate it, and when it’s time to consult your dentist.
What is a Tooth Filling?
Tooth fillings are temporary or permanent structures installed into a damaged tooth. They are intended to fill the space caused by damage such as cavities or a cracked tooth. They generally are permanent, but temporary fillings can be installed as placeholders until a permanent filling can be put in. Permanent fillings are made to look like the color of natural teeth so that they are not noticeable in the mouth.
What Causes Tooth Sensitivity After a Filling?
Tooth sensitivity after a filling is not uncommon and usually is only temporary. It happens when the nerves inside the tooth become irritated or inflamed. This can occur for several reasons:
- Temperature Sensitivity: One of the most common reasons for sensitivity after a tooth filling is caused by heightened sensitivity to hot or cold foods and beverages. The filling procedure itself involves drilling into the tooth. This can temporarily expose the inner layers, making the tooth more sensitive to temperature changes.
- Nerve Sensitivity: Sometimes, a deep filling can be placed near the nerve of the tooth. This can cause it to react more sensitively. The process of installing a filling can also cause minor irritation to the tooth’s nerve, leading to temporary sensitivity.
- Changes in Bite Alignment: Dentists go to great lengths to fit the tooth filling perfectly in the mouth. Sometimes the filling doesn’t perfectly align with the surrounding teeth, however. This can put pressure on the affected tooth when the person bites down. This can cause discomfort and contribute to tooth sensitivity.
- Material Reaction: Different materials are used for fillings, such as amalgam or composite resin. Some materials may cause slight irritation to the surrounding tissues, leading to sensitivity.
- Tooth Healing: After a filling is placed, the person’s tooth may need time to heal from the procedure. In the first few days or weeks, the person might experience some discomfort as the tooth adjusts to the filling.
How Can I Manage Sensitivity after a Tooth Filling?
Tooth sensitivity will often subside on its own in a few to several days. There are several steps a person can take to reduce discomfort in the meantime. Try to avoid eating very hot or cold foods or drinks until the sensitivity diminishes. Use toothpaste for sensitive teeth.
Be gentle when brushing. Use a soft-bristled toothbrush and brush gently around the filling area.
If the sensitivity does not subside on its own in a few days, is not manageable with over-the-counter pain medications, or you suspect the sensitivity is due to an issue with your bite alignment, contact your dentist.
