Visiting a Dentist

It is important to check your oral cavity status. So, visiting a dentist for a routine oral hygiene checkup is necessary.

It keeps all tooth infections at bay & helps repair any damages done before disease progression.

Moreover, your dentist performs X-rays to confirm the diagnosis based on the signs and symptoms.

In case of an emergency, you can always share these with your dentist, before the appointment.

This will help you get a detailed treatment plan and accurate cost estimate.

Treatment Options

Depending on the case, age, cause, and underlying health conditions, your dentist prescribes: [7]

  • Antibiotics for infection
  • Painkillers to ease the pain

Some elective procedures are also done like:

  • Scaling & root planing
  • Fillings or root canal treatment
  • Extractions & abscess drainage

These procedures are performed by professionals as needed.

So, make sure you practice good oral hygiene measures.

Call or visit your dentist if you experience any symptoms of a dental infection.
