Toothache is usually caused by problems such as tooth decay, infection, gum disease, or a cracked tooth. While some temporary home measures may reduce discomfort, persistent tooth pain should always be checked by a Dentist to identify and treat the underlying cause.
Common Causes of Toothache
Toothache can develop for several different reasons. In many cases, the pain occurs when the inner part of the tooth becomes irritated or inflamed.
Common causes of toothache can include:
Tooth decay (cavities)
Infection inside the tooth
A cracked or damaged tooth
Gum disease or gum inflammation
Food trapped between teeth
Teeth grinding or clenching
Sometimes tooth pain can start suddenly, while in other cases it develops gradually over time. Even mild discomfort can be a sign that something needs attention.
Temporary Ways to Relieve Toothache at Home
While home remedies cannot treat the underlying dental problem, there are a few simple steps that may help reduce discomfort temporarily until you can get to a Dentist.
These include:
Gently brushing and cleaning between the teeth to remove trapped food
Rinsing with warm salt water to help soothe irritated gums
Avoiding very hot, cold, or sugary foods which may trigger sensitivity
Taking over-the-counter pain relief if appropriate and following the instructions provided
These measures may help reduce symptoms in the short term, but they do not treat the cause of the pain. If toothache continues, it’s important to arrange a dental examination as soon as you can and if you are in a lot of pain you should book an Emergency Dental Appointment. Fortunately at tooth dental in Waterloo, we usually have same day Emergency appointments available to help you.
Why Does Toothache Feel Worse at Night?
Many people notice that toothache seems to become more intense in the evening or when lying down. This can happen for a few reasons.
When you lie flat, blood flow to the head increases slightly, which can put additional pressure on inflamed tissues inside the tooth. This may make pain feel more noticeable.
At night there are also fewer distractions, so discomfort that might be manageable during the day can feel stronger when trying to sleep.
If toothache is disturbing your sleep, it may help to:
Keep your head slightly elevated with an extra pillow
Avoid very hot, cold, or sugary foods before bed
Gently clean around the tooth to remove trapped food
Take appropriate over-the-counter pain relief if needed
However, it’s important to arrange a dental examination so the underlying cause can be properly treated.
Why You Shouldn’t Ignore Toothache
One of the most common causes of toothache is tooth decay. When a cavity develops, bacteria gradually damage the tooth structure. In the early stages, this can usually be treated with a simple filling.
However, if decay progresses deeper into the tooth it can eventually reach the nerve, which may lead to more severe pain and infection.

Early treatment is often quicker, simpler, and less invasive than waiting until symptoms become more severe.
When Should You See a Dentist for Toothache?
Tooth pain is a clear sign that something may not be right, so it’s always sensible to have it checked.
You should arrange a dental appointment if you experience:
Tooth pain lasting longer than one or two days
Severe or worsening pain
Pain when biting or chewing
Swelling around the tooth or gums
Sensitivity to hot or cold that does not improve
A Dentist can examine the tooth, identify the cause of the pain, and recommend the most appropriate treatment.
Preventing Toothache
The best way to avoid toothache is by preventing dental problems before they develop. As Principal Dentist at tooth, I know that when it comes to dentistry, prevention is better (and much cheaper!) than cure.
This usually involves:
Brushing twice daily with fluoride toothpaste
Cleaning between the teeth with floss or interdental brushes
Maintaining a balanced diet and limiting sugary foods
Attending regular dental check-ups
Routine examinations allow dentists to identify early signs of decay or gum disease before they begin causing pain.
At tooth, we focus on preventative care and helping patients maintain healthy teeth and gums through regular check-ups and personalised advice.
It’s quick and easy to book for a dental check up or a dental emergency appointment. We are here to help and open early to late, so don’t suffer in silence, click one of the buttons below to book now or ask a question.
