What are the causes of tooth sensitivity after fillings and what are the effective remedies?

Tooth filling is a common dental treatment, but some patients experience unexplained sensitivity afterward. Let’s explore causes and effective remedies with The East Rose Dental Clinic to help you identify issues early and minimize unnecessary risks.

Is Tooth Sensitivity Common After Filling?

Some individuals may experience sensitivity after a dental filling, but this is not a common occurrence. If the tooth is only slightly damaged and the filling procedure goes smoothly, patients typically do not feel sensitivity or pain afterward. However, if the tooth has significant damage or if the filling process is complicated, the sensitivity may persist after the anaesthesia wears off.
Tooth filling is a safe dental treatment that does not harm your health. If sensitivity does occur, it usually lasts for about 1 to 2 weeks and will resolve on its own. However, if the sensation continues for an extended period, it’s advisable to return to the dentist for an evaluation and timely treatment to prevent more serious issues.

6 Main Causes of Tooth Sensitivity After Filling

After a dental filling, sensitivity can occur due to various reasons. Understanding these causes will help you proactively prevent and address issues while ensuring your oral health. Here are the common reasons for sensitivity after a filling.

Incomplete treatment of tooth pulp

For patients with severe tooth decay affecting the pulp, it is essential to fully treat pulpitis before proceeding with a filling. Overlooking this step and placing a filling without addressing the pulp issue can lead to pain and sensitivity. Moreover, untreated pulpitis can lead to abscesses, causing infection in the surrounding area and worsening the dental condition, ultimately impacting overall oral health.

Incomplete and improper filling technique

Not thoroughly cleaning tooth decay before filling can lead to sensitivity, especially in molars. Additionally, improper filling techniques can lead to gaps in the filling, allowing food particles to enter during chewing. This not only causes irritation but can also prolong tooth sensitivity. Over time, the accumulation of food can increase the risk of infection, leading to more severe issues, such as tooth loss, if not addressed promptly. Correct execution of the filling procedure is crucial for maintaining oral health and preventing complications.

Compression of Filling Material in the Cavity

When the filling material compresses into the cavity, the movement of dentinal fluid within the dentinal tubules can lead to discomfort. During the light curing process, the material may shrink, resulting in gaps between the filling and the tooth structure. The dentinal fluid will fill this gap, but as you chew, the fluid continues to move, leading to sensitivity. This is one of the common causes of sensitivity after improper dental fillings.

Incomplete Cleaning of the Cavity

Before filling a tooth, the dentist must thoroughly clean the decayed area to prevent bacteria from continuing to grow. If the dentist fails to adequately clean the cavity, bacteria could cause further damage to the tooth pulp, resulting in prolonged sensitivity. In some cases, monitoring and checking for irritation may be necessary for a few days after the filling. Thoroughly cleaning the cavity is essential to ensure the effectiveness of the filling and to prevent future complications.

Allergic Reactions to Filling Materials

Another cause of sensitivity after dental fillings is an allergy to the filling materials. Substances that are of unknown origin or not suitable for your body can trigger an irritating reaction, resulting in pain and discomfort. This phenomenon often appears immediately after the filling procedure and can persist if not addressed promptly. Therefore, it is crucial to choose safe and suitable filling materials to ensure oral health.

Oral care after dental fillings

After a dental filling, maintaining proper oral care is crucial to prevent sensitivity. Specifically, for the first two hours after the procedure, you should avoid eating or drinking to allow the filling to stabilize completely. An improper diet and hygiene can irritate the filling, leading to sensitivity and discomfort. Therefore, proper oral care is a key factor in determining any conditions that may arise following the filling treatment.

What to Do If Your Filling Causes Sensitivity?

To quickly alleviate sensitivity at home after a dental filling, you can try some simple remedies, such as applying ginger or garlic to the affected area to provide temporary pain relief. Additionally, rinsing your mouth with diluted saltwater can help reduce inflammation and fight bacteria. You may also apply a warm or cold compress to the sensitive area to ease discomfort. However, these methods are only short-term solutions and do not address the underlying causes.

If the sensitivity persists, you should visit your dentist for timely examination and treatment. If the old filling is causing irritation or improper placement, the dentist may need to remove it before refilling the tooth. If the sensitivity is due to untreated decay or pulpitis, the dentist will clean and treat the pulp before refilling. To prevent recurrence of sensitivity, the dentist will provide guidance on proper oral care and monitor your dental condition during regular follow-up visits.

Some Tips to Minimise Sensitivity After Dental Filling

Sensitivity after a dental filling is a common issue. However, there are certain precautions you can take to ensure effective recovery at the filling site. Specifically:

• Avoid Extremely Hot or Cold Foods: After a filling, your teeth may be more sensitive to temperature changes. Consuming very hot or cold foods can irritate the area, leading to sensitivity. Limit the intake of iced drinks, hot coffee, and extreme temperature foods to avoid putting stress on the filling.
• Use Toothpaste for Sensitive Teeth: Toothpaste formulated for sensitive teeth contains ingredients that help protect enamel and reduce sensitivity. It’s advisable to use this type of toothpaste in the weeks following your filling to help your teeth adjust to the filling material and prevent irritation.
• Avoid Hard and Chewy Foods: In the initial days after your filling, avoid chewing hard or chewy foods such as gum, grilled meat, or ice. Chewing forcefully can put pressure on the filling, making it more susceptible to loosening or cracking, which can cause pain and necessitate adjustments to it.
• Gentle oral care and the use of dental floss: Brushing gently with a soft toothbrush helps keep your teeth clean without damaging the filling. You should also use dental floss to clean between your teeth without applying too much pressure to the newly filled area. This helps prevent bacterial buildup and protects your oral health from infection.
• Use pain relief medication as prescribed by your doctor: In cases of excessive sensitivity, your dentist may prescribe pain relief medication to help you feel more comfortable. However, it’s important to follow the prescribed dosage and duration to ensure both effectiveness and safety.
• Choose a Reputable Dental Clinic: Ensure that you have your filling done at a reputable dental clinic with skilled professionals. East Rose Dental uses safe filling materials and employs highly qualified dentists to ensure a tight seal between the filling and the tooth, preventing gaps that can lead to sensitivity or other complications.
