Lamar Jackson has cosmetic dental work on his natural teeth to straighten and brighten them, including possible orthodontic treatment (such as clear aligners) and professional teeth whitening. He also wears removable custom- fitted gold and diamond grillz, which are jewel-encrusted caps that cover his teeth temporarily, enhancing the appearance. These grillz are not permanent dental fixtures but rather decorative accessories. Jackson's teeth appear healthy, with no signs of decay, and his current stellar smile is a result of cosmetic dentistry combined with stylistic grillz use.
