Does getting a cavity filled hurt?

 
 
 
 

As dentists we are often asked 'Does getting a cavity filled hurt?’. When answering this question we like to provide patients with as much information about the procedure and common side effects as possible.

Will I need a filling?

According to the Australian Institute for Health and Welfare, most Australian adults have some experience of dental decay (1). A 2017 – 2018 survey found that fewer than 11% of adults had no experience of dental decay in their permanent teeth (1). This means that despite advances in dental technology and the prevention of disease, most patients will have at least one filling during their lifetime. 

Why might I need a filling?

The most common reason for a filling is to treat decay. However, a filling may also be required to:

  • Repair a chip

  • Bond over cracks; or

  • Improve the strength or aesthetics of a tooth.

The above issues may be found when your dentist does an x-ray on your mouth.  

 

Different types of cavities which may need a filling 

 

Will I need an injection?

To help you avoid pain during the procedure your dentist will usually administer local anaesthetic.  This will only affect the area being treated, it will not put you to sleep (2). Administering the anaesthetic does require an injection. However, it is made as comfortable as possible by using a computerised delivery system and anaesthetic gel.In some cases, an anaesthetic injection is not required. This might be if:

  • The defect or cavity is small

  • The tooth has had prior root canal treatment

  • You have thick dentine protecting the nerve

  • The tooth is not sensitive

  • You have a high threshold for discomfort

What is the process of filling the cavity?

Fillings can range from small superficial reconstructions to a full tooth rebuild. Generally, the steps are quite similar for most fillings, however, the length of the procedure will vary based on the size and anatomical challenges of the filling.After the suitable anaesthetic has been administered the process your dentist will follow for filling your cavity generally is:

  • Removing any decay and weakened tooth structure

  • Removing any old, deteriorated fillings in the tooth

  • Cleaning and preparing the tooth to give a fresh surface for bonding the filling

  • Applying a frame or formwork to help contour the filling

  • Layering the filling material in increments and setting each layer

  • Checking and adjusting the shape of the filling so the patient can bite and chew comfortably

  • Ensuring the filling is smooth so that it doesn’t trap plaque or annoy the tongue

What happens after the cavity has been filled?

Modern fillings generally set immediately, so it is okay to eat after having a dental filling done. However, if you have had an anaesthetic, you will need to be careful not to accidentally bite your tongue, cheeks or lip while numb. You may wish to use the other side of your mouth to chew your food or stick to soft foods in the hours directly following your procedure.

As the anaesthetic starts to wear off you may experience a tingly feeling in your mouth. Some patients also report tooth sensitivity. Usually, this fades after a few days.

Over the counter pain relief can help in managing the discomfort. In addition, avoiding hard or sticky foods may help (2).

It’s a good idea to see your dentist again if the discomfort persists longer than a week or gets worse with time. 

How can I avoid needing a cavity to be filled?

As much as possible we encourage our patients to prevent a cavity from forming. A few simple measures you can take to reduce the risk of cavities is:

  • Brushing your teeth for two minutes twice a day

  • Using dental floss once a day

  • Sipping water frequently

  • Eating a well-balanced diet

  • Reducing the frequency of sugary snacks
