A small cavity in the early stage means the tooth has just started to decay, and this is the best time to treat it before it becomes deeper or painful. At this stage, you may not feel much discomfort, but the decay can slowly spread if left untreated. Early care can often stop the problem from getting worse and help preserve your natural tooth. The appropriate treatment depends on how early the cavity is detected. If it is very superficial, your dentist may suggest applying fluoride or remineralisation to strengthen the tooth and prevent further damage. If a small hole has already formed, a simple filling is usually used to remove decay and restore the tooth. These treatments are quick, safe, and help prevent the need for more complex procedures later. You can also protect your teeth by maintaining good oral hygiene. Brush twice daily with fluoride toothpaste, reduce sugary foods, and rinse your mouth after meals. Avoid delaying treatment, as early cavities are easier and less costly to manage. A dental check-up can confirm the stage and help you choose the right option.
