Are naturally white permanent teeth always weak and do people with such teeth always have decayfillingsdental work by the age of 20 if the eat anything sweet?

Naturally white permanent teeth are not inherently weak, and their strength largely depends on genetics, oral hygiene, and dietary habits rather than color alone. Individuals with white teeth can maintain strong dental health by practicing good oral care and moderating sugar intake. While consuming sweets can increase the risk of decay, it doesn't guarantee that someone will have fillings or dental work by age 20. Regular dental check-ups and a balanced diet play crucial roles in preventing cavities, regardless of tooth color.
