If you have persistent or severe tooth pain in Yishun, arrange a dental assessment to identify the cause. Toothache may be caused by tooth decay, a cracked tooth, dental infection, gum problems or wisdom teeth, and treatment depends on the diagnosis.
Polygems Dental Care has two dental clinics in Yishun at Blk 507 and Blk 675 Yishun Avenue 4. Same-day appointments for dental pain may be available, subject to the clinic schedule.**
Seek prompt dental attention if tooth pain is accompanied by swelling, fever, significant pain when biting, difficulty eating, or pain that prevents you from sleeping.
Not every toothache requires emergency treatment, but certain symptoms should be assessed promptly.
Contact a dentist if you experience:
Significant facial or neck swelling accompanied by difficulty breathing or swallowing requires urgent medical attention.
If you are uncertain about the seriousness of your symptoms, a dental assessment can help establish the likely cause and appropriate next step.
If you are experiencing tooth pain, it is advisable to arrange a dental assessment so that the underlying cause can be identified. Toothache may arise from several dental conditions, including tooth decay, a cracked tooth, inflammation of the dental pulp, gum infection or problems involving a wisdom tooth.
While waiting for your dental appointment, the following measures may help to reduce irritation or discomfort:
These measures are intended only for temporary comfort and do not treat the underlying dental condition.
Seek prompt dental attention if the pain is severe, persistent, repeatedly disturbs your sleep, or is associated with facial swelling, fever, difficulty opening the mouth or increasing discomfort.
Patients experiencing persistent or worsening tooth pain may arrange a dental assessment at either of our Yishun clinics at Blk 507 Yishun Avenue 4, #01-06, Singapore 760507 *, or Blk 675 Yishun Avenue 4, #01-04, Singapore 760675.*
Urgent medical attention should be sought if swelling is affecting breathing or swallowing.
Tooth pain, commonly known as a toothache, can range from mild sensitivity or discomfort to severe, persistent pain that affects eating, speaking and sleeping. It may be caused by tooth decay, a cracked tooth, dental infection, gum problems, impacted wisdom teeth or other dental conditions.
The symptoms of toothache can vary depending on the underlying cause. Tooth pain may be constant or intermittent and can sometimes spread to the surrounding teeth, jaw or face.
Common symptoms include:
The intensity of the pain does not always indicate how serious the underlying dental problem is. A proper dental examination is therefore important when tooth pain persists or repeatedly returns.
There are many possible causes of tooth pain. Identifying the source of the discomfort is important because treatment depends on the underlying dental condition rather than the pain alone.
Tooth decay occurs when bacteria and acids gradually damage the tooth structure. In its early stages, decay may cause little or no discomfort.
As the cavity becomes deeper, the tooth may become sensitive to sweet, hot or cold foods and drinks. If decay progresses towards the dental pulp, where the nerves and blood vessels of the tooth are located, the pain may become more persistent or severe.
Depending on the extent of the decay, treatment may involve a dental filling, root canal treatment or, in some circumstances, extraction.
A dental abscess is an infection involving a tooth or the tissues surrounding it.
It can develop when bacteria enter the inside of a tooth through deep decay, a crack or other damage. Infection may cause persistent or throbbing tooth pain, tenderness, swelling, an unpleasant taste in the mouth and sometimes fever.
A dental infection should be assessed promptly because the infection may spread into the surrounding tissues if left untreated.
Treatment depends on the source and severity of the infection and may include drainage, root canal treatment, extraction or other appropriate dental treatment.
A tooth can crack or fracture because of trauma, biting on something hard, large existing restorations, repeated teeth grinding or general weakening of the tooth structure.
Some cracks cause sharp pain when biting or releasing pressure, while others may result in sensitivity to hot or cold temperatures.
Symptoms can sometimes come and go, making cracked teeth more difficult to identify without a proper dental examination.
Treatment depends on the location and extent of the crack and may range from a restoration or crown to root canal treatment or extraction when the tooth cannot be predictably restored.
Wisdom teeth are the last permanent teeth to develop at the back of the mouth. When there is insufficient space for them to erupt normally, they may become partially erupted or impacted beneath the gum or bone.
An impacted or partially erupted wisdom tooth can contribute to pain, swelling, food trapping and inflammation of the surrounding gum.
In some cases, the neighbouring tooth may also be affected.
A dental examination and X-ray can help determine the position of the wisdom tooth and whether monitoring, cleaning, medication or wisdom tooth removal may be appropriate.
Not all tooth pain comes directly from the tooth itself.
Inflamed or infected gums can sometimes cause tenderness and discomfort around the teeth. Gum problems may be associated with redness, swelling, bleeding, sensitivity or discomfort when chewing.
A dental examination can help determine whether the pain originates from the tooth, gums or supporting tissues.
A short, sharp sensation when consuming cold, hot, sweet or acidic foods may be related to tooth sensitivity.
Possible causes include exposed root surfaces, enamel wear, gum recession, tooth decay, cracks or existing dental restorations.
Because sensitivity can have several causes, persistent or worsening sensitivity should be assessed before deciding on the appropriate treatment.
Different dental conditions can produce very similar symptoms, so the location of the pain alone may not always identify the affected tooth.
During your dental examination, your dentist may ask questions such as:
The dentist will then examine the teeth, gums and surrounding tissues.
Depending on the findings, additional tests or dental X-rays may be recommended to help identify problems such as decay, infection, cracks, impacted wisdom teeth or changes around the roots of the teeth.
The goal is to identify the source of the pain before recommending treatment.
There is no single treatment for every toothache.
Treatment depends on the cause of the pain, how extensively the tooth is affected and whether the tooth can be predictably restored.
When tooth decay is identified before extensive involvement of the dental pulp, the damaged tooth structure may be removed and restored with a dental filling.
Treating decay before it progresses further may help preserve more of the natural tooth structure.
If the dental pulp becomes severely inflamed or infected, root canal treatment may be considered when the tooth is suitable for restoration.
During root canal treatment, inflamed or infected tissue inside the tooth is removed before the root canal system is cleaned, disinfected and sealed.
The aim is to manage disease within the tooth while retaining the natural tooth where clinically appropriate.
When tooth pain originates from an impacted or partially erupted wisdom tooth, treatment depends on its position, the surrounding tissues and the symptoms experienced.
Some wisdom teeth can be monitored, while others may require removal when they repeatedly cause pain, infection or other dental problems.
A tooth may occasionally be too extensively damaged, infected or fractured to be predictably restored.
When extraction is considered appropriate, the available treatment options should first be discussed so that the patient understands the reasons for the recommendation.
When discomfort arises primarily from inflammation or infection of the gums and supporting tissues, treatment may involve professional cleaning and management of the underlying gum condition.

Sudden tooth pain can have several possible causes, including tooth decay, a cracked tooth, inflammation of the dental pulp, infection, gum problems or an impacted wisdom tooth.
If the pain appears suddenly, repeatedly returns or becomes increasingly severe, a dental examination can help determine the underlying cause.
Pain when biting may occur with tooth decay, a cracked tooth, inflammation around the root of a tooth or problems involving an existing filling or restoration.
Several dental conditions can cause similar symptoms, so an examination may be necessary to identify the affected tooth and determine the cause.
Sensitivity to hot or cold temperatures may be associated with exposed root surfaces, enamel wear, tooth decay, cracks or inflammation of the dental pulp.
Brief sensitivity and pain that continues after the hot or cold stimulus has been removed can have different causes. Persistent symptoms should therefore be assessed.
Yes. Impacted or partially erupted wisdom teeth can cause pain and swelling at the back of the mouth.
Food and bacteria may become trapped around a partially erupted wisdom tooth and contribute to inflammation of the surrounding gum. A dental examination and X-ray can help determine the tooth's position and whether treatment is required.
Not necessarily.
Severe tooth pain has several possible causes, and root canal treatment is only one potential treatment. The dentist first needs to determine whether the dental pulp is affected and whether the tooth is suitable for restoration.
Antibiotics are not required for every toothache.
Dental pain can arise from tooth decay, cracks, pulp inflammation and other conditions that require dental treatment rather than antibiotics alone. A dentist will determine whether antibiotics are clinically indicated based on the diagnosis and signs of infection.
Some tooth pain may temporarily improve, but disappearance of the pain does not necessarily mean that the underlying dental problem has resolved.
Symptoms from a damaged or infected tooth can change over time. Persistent, recurrent or severe tooth pain should therefore be assessed.
Consider arranging a dental assessment when tooth pain persists, repeatedly returns, becomes increasingly severe or is accompanied by swelling, fever, pain when biting or difficulty eating.
Earlier assessment allows the cause to be identified and appropriate treatment options to be discussed before the problem becomes more complicated.
Same-day dental appointments may be available at Polygems Dental Care depending on the clinic schedule and appointment availability.

Tooth pain does not always come from the tooth that appears to hurt. During an examination, we consider the pattern of pain together with clinical findings — such as whether discomfort is triggered by biting, temperature, pressure or occurs spontaneously. Dental X-rays and other tests may be recommended where clinically indicated to help distinguish between problems such as decay, cracks, pulp inflammation, wisdom teeth and gum-related conditions.
