Yes, it is possible to save an over-spiced dish. Sometimes. Here are a few tips:

Dilute: One of the simplest ways to reduce the spiciness of a dish is to dilute it with more non-spicy ingredients. For example, you can add more liquid (such as water or broth) to a soup or sauce that is too spicy. This will help to spread out the spiciness and make it milder.

Add sweetness: Adding a sweet ingredient like sugar or honey can help balance out the spiciness. This is because sweetness can counteract the heat and provide a pleasant contrast to the spice. However, be careful not to overdo it, as too much sweetness can make the dish taste unbalanced.

Add acidity: Acidity can also help to balance out the spiciness of a dish. Try adding a squeeze of lemon or lime juice, a splash of vinegar, or some chopped tomatoes. The acidity can help to cut through the heat and provide a more well-rounded flavour.

Add dairy: Dairy products like milk, cream, or yogurt can also help mellow out a dish’s spiciness. The fat in dairy can help to absorb the heat and reduce its intensity. You can add a dollop of sour cream or a splash of milk to a spicy soup or curry.

Add starch: Adding starchy ingredients like potatoes, rice, or bread can also help to absorb the spiciness. The starch can help to neutralize the heat and make the dish more palatable. For example, you can serve a spicy curry over a bed of rice or add some diced potatoes to a spicy soup.

Remember to adjust the other seasoning in the dish to maintain a balanced flavour after making adjustments.
