The ideal time to undergo teeth whitening is when your oral health is in good condition and you’re free from dental issues. It’s recommended to consult with a dentist before scheduling a whitening procedure to ensure your teeth and gums are in optimal shape. It can be effective at any time of year, but many people consider getting it done before significant events like weddings, graduations, or special occasions. Remember that results vary, so discussing your goals and expectations with a dental professional will help determine the best time to achieve a brighter, more confident smile.
