You cannot fully remove tooth decay yourself once cavities have formed, as professional dental treatment is necessary to repair the damage. However, you can manage early tooth decay and potentially reverse it before it progresses to cavities through several home care methods focused on remineralization and reducing bacteria:

• Maintain excellent oral hygiene by brushing twice daily with fluoride toothpaste and flossing daily to remove plaque that causes decay

• Use fluoride treatments such as fluoride toothpaste, mouth rinses, or professional fluoride applications to strengthen and remineralize enamel, which can stop or reverse early decay

• Oil pulling with coconut or sesame oil by swishing for about 20 minutes may reduce harmful bacteria and plaque, supporting oral health

• Rinse with diluted hydrogen peroxide or salt water to reduce bacteria and inflammation in the mouth

• Use baking soda as a mild abrasive and acid neutralizer to help remove plaque and reduce acid that erodes enamel

• Chew sugar-free gum to stimulate saliva production, which naturally washes away food particles and buffers acids

• Avoid sugary and starchy foods that feed decay-causing bacteria, and eat a balanced diet rich in calcium, phosphorus, and vitamin D to support enamel repair

These home remedies can help slow or stop early tooth decay but do not cure cavities or advanced decay. For any persistent toothache, visible holes, or advanced decay, you must see a dentist for treatments such as fillings, crowns, or root canals

. In summary, while you cannot remove tooth decay completely by yourself once cavities form, you can prevent progression and promote remineralization of early decay through good oral hygiene, fluoride use, dietary changes, and natural remedies. Regular dental visits remain essential for diagnosis and professional care.
