Sensitive teeth: why the zing happens — and how we calm it
A brief zing or lingering sensitivity can make eating uncomfortable. Exposed root surfaces, decay, cracks and problems with fillings are among the possible causes. The right treatment starts with finding out which applies.
This page can’t diagnose you. Similar symptoms can have different causes. A dentist uses your history, an examination and any appropriate tests to explain what is happening and what care you need.

Cold sensitivity or exposed roots
Receding gums, tooth wear or other changes can expose sensitive surfaces. A short-lived zing does not prove the tooth is healthy inside, and the appearance alone cannot establish the cause.
What you should do
Contact reception to arrange an assessment and describe your symptoms. Ask how soon you should be seen; new swelling, severe pain or an injury needs urgent advice.
Options for reducing sensitivity
Depending on the findings, your dentist may discuss a desensitising toothpaste, fluoride treatment, brushing changes or covering a damaged area. Improvement varies and follow-up may be needed.
- A filling may be appropriate where decay or a damaged surface needs repair.
What you should do
Arrange a dental assessment to discuss the cause and options. Tell reception if pain, swelling, injury or a recent change makes the problem more urgent.
If decay is involved
The depth of decay and the condition of the pulp affect the options. Treating decay does not automatically require root canal treatment, but a filling is not suitable for every tooth.
- A filling restores a suitable cavity after assessment.
- A protective pulp treatment may be considered for a suitable tooth with deep decay. The dentist explains the chances of healing and possible further treatment.
What you should do
Contact reception to arrange an assessment and describe your symptoms. Ask how soon you should be seen; new swelling, severe pain or an injury needs urgent advice.
Sensitivity that lingers or pain that starts on its own
Lingering pain, night-time pain or symptoms that are getting worse need prompt assessment. They can occur with pulp inflammation or other problems; the pattern alone cannot confirm the diagnosis or whether the pulp can recover.
What you should do
Contact reception for urgent dental assessment. If we are closed or cannot see you promptly, contact another available dentist. Do not wait for a WhatsApp reply if symptoms are worsening.
What it costs
We quote before we treat. Ask reception about consultation fees and your medical aid. Cover depends on your scheme, plan and available benefits; co-payments may apply. Confirm benefits and any required authorisation before treatment.
On a medical aid? Understand medical aid and treatment quotes — then check your plan’s benefits and any authorisation with your scheme. A benefit check is not a guarantee of payment.
