8. Teeth Whitener
This tip is well-known all around the globe. That’s one of the cheapest and most affordable methods of whitening teeth at home. You’ll need some lemon juice and soda. Prepare a paste and apply it on your teeth using a Q-tip. This method is harsh if used too often. Be careful and do not ruin your tooth enamel. The longest you can leave the paste on your teeth is no more than one minute. Thoroughly wash your mouth with warm water after the procedure.
