Hello & welcome,
You are putting yourself in the risk by carrying cracked or fractured tooth in the oral cavity.
This is because such teeth are more prone to get infected severely & may affect general health.
Even if filling is intact there, this tooth must be posted for extraction as soon as possible by your dentist
You can visit your physician & ask for proper prescription of Antibiotics & painkillers to delay the extraction till your dentist returns back.
But frankly speaking this would not be a good choice according to me.
Instead visiting another dentist in your area & getting the tooth extracted will be preferred anytime.
Avoid hot fomentation or even warm food stuff as they may aggravate the pain & may initiate the swelling.
