How Long Does It Take to Recover from Wisdom Teeth Removal Surgery?
The time it takes to recover from a wisdom tooth extraction can vary depending on factors like your age and whether any were impacted. Recovery typically takes between 3 days and 2 weeks. Wisdom teeth, or third molars, are the last adult teeth to emerge in your mouth. They erupt on the top and bottom of both sides, usually when you're between the ages of 17 and 25. Nearly 5 million wisdom tooth extractions are performed every year in the United States. Half of these surgeries involve removing all four wisdom teeth. Although surgery is common, the recovery period will vary in length depending on: how many teeth were extracted your age if a tooth was impacted, which means it hasn't emerged from below the gums yet or isn't visible if complications occurred during the surgery Read on to learn what you can expect in the two weeks following wisdom tooth removal. What is the timeline for recovering from wisdom tooth removal? Day 1 Wisdom teeth extraction is an outpatient surgery that usually takes about 1 hour. The oral surgeon will give you local anesthetic, and general anesthetic or sedation (nitrous or IV sedation) may be used if you are anxious. After the surgery, you'll gradually regain feeling in your mouth as the anesthetic wears off. Common symptoms to expect include: swelling, pain, and blood in your mouth swelling and mild cheek bruising trismus, sometimes called lockjaw a weird taste in your mouth numbness, tingling, or a lack of sensation in your mouth, cheeks, or face If you will have sedation during your procedure, it's important to have someone drive you home after the surgery. If you experience severe pain or excessive bleeding, contact your oral surgeon and get immediate medical attention. Days 2–4 The swelling, pain, and bruising in your mouth and cheeks may increase over the next few days. To rest, it's recommended that you take at least 1–2 days off from work or school. Gradually, your symptoms will plateau and then subside. Once they are manageable, you may return to work or school. If pain, bleeding, or oozing at the extraction site significantly increases, contact your oral surgeon or a healthcare professional immediately. Days 5–14 By the end of day seven, most people are near the end of their recovery. This might feel like: very minimal swelling, bruising, and pain in your mouth and cheeks near-normal jaw mobility no more tingling, bleeding, or bad taste in your mouth gradually returning to physical activity If your third molars were impacted, came in at an awkward angle, or there were complications during the surgery, it may take you up to 2 weeks to recover. Days after surgery Symptoms to expect 0–1 • swelling, pain, and bleeding in mouth • swelling and mild bruising in cheeks • stiff, sore jaw • weird taste in mouth • numbness, tingling, or a lack of sensation in mouth, cheeks, or face 2–4 • increased swelling and bruising in cheeks • stiff, sore jaw • reduced bleeding in mouth • slow return to daily activities and work 5–14 • decreased swelling, bruising, and pain in mouth and cheeks • near-normal jaw mobility • no more tingling, bleeding, or bad taste in mouth • gradual return to physical activity What are the possible complications of wisdom removal surgery? Dry sockets might happen 3–5 days after surgery. This is when the natural blood clot that forms in the extraction site is removed or dislodged before the site is healed, exposing bone or nerves. Damage to the inferior alveolar or lingual nerves, the nerves that run along your lower jaw, is also possible, though this is less common. Get medical help if you experience any of these symptoms: trouble swallowing or breathing fever your medication is not effective at dulling the pain swelling, tingling, or numbness getting worse over time blood or pus coming out of your nose bleeding at the extraction site that doesn't stop when you hold gauze to it and apply pressure What self-care and home remedies can you do to help recover from wisdom tooth removal? Activity It's important not to dislodge the blood clots forming in the back of your mouth or irritate the stitches. Like any scab, the blood over your wisdom tooth hole protects and heals the wound. During the first 24 hours, avoid: drinking alcohol, caffeine, and hot drinks chewing food using a straw smoking using tobacco products or vaping rinsing your mouth or spitting After the first 24 hours have passed, you may resume daily activities, but avoid doing anything that could dislodge stitches or the blood clot over your wound. This includes: heavy lifting or strenuous exercise smoking swishing or spitting drinking from a straw chewing hard or chewy food Once the pain and swelling have gone down, you can gradually start exercising again. That said, if you play contact or high intensity sports, speak with an oral surgeon to determine the best timeline for you to resume activity. Oral hygiene Properly caring for your mouth will help prevent infections and complications. After your surgery, you will have gauze in your mouth. Your oral surgeon will give you exact instructions on how best to clean and protect your mouth during recovery. This might be the only time your oral surgeon tells you not to brush, rinse, or floss for a whole day! After leaving your mouth alone for the first 24 hours, common cleaning instructions include: Gently rinse your mouth with salt water or an antiseptic mouthwash. Do not swoosh the liquid or spit it out. Instead, move your head from side to side, then tip your mouth over the sink to let the water fall out. Gently brush and floss the rest of your teeth. Gently dab the wound with gauze to absorb excess blood. How can you manage pain after wisdom tooth removal? The main ways to manage pain and reduce swelling are by icing the area and taking pain medication. Your oral surgeon may prescribe pain medication or antibiotics. These can help with pain, inflammation, and to prevent infections. Carefully follow the instructions provided and complete your whole course of antibiotics. Alternatively, they might recommend over-the-counter medications, such as ibuprofen or acetaminophen. Some home remedies, such as icing the affected area or using an extra pillow at night, may also help relieve the pain and discomfort. What can you eat and drink after wisdom tooth removal? Staying hydrated and eating well is important for recovery. Speak with your oral surgeon about what you can eat starting the day after surgery. Remember, you don't want to disrupt your blood clot or stitches. Start with very soft food, such as: cottage cheese applesauce pudding soup mashed potatoes smoothies When eating, avoid: very hot or cold foods nuts or seeds that could get stuck in the extraction hole drinking from a straw or slurping vigorously from a spoon hard, crunchy, or spicy foods After a few days, when you start to eat heartier food, chew with your other teeth. After eating, remember to gently rinse your mouth. Frequently asked questions How many days should I take off for wisdom teeth recovery? It's recommended to take a minimum of 2 days off from work or school, including the date of your surgery. But if your job requires physical exertion, you'll want to consider taking 3–4 days off. It's very important to gradually return to work and your daily activities. It's recommended to take a minimum of 2 days off from work or school, including the date of your surgery.

Stranded in hell: How people are extracted from war zones
Photo: JACK GUEZ It is dangerous, diplomatically delicate and extremely expensive. Getting a New Zealander out of a war zone can cost $1 million if they're injured. It often takes high level negotiations with top secret contacts and New Zealand often has to ask favours of other friendly countries to get its citizens to safety. "It's a very tricky business to exfiltrate or extract or save New Zealanders abroad in other countries' jurisdictions," says Stephen Hoadley, retired Auckland University professor of political science. "They are hosts to New Zealanders but they don't expect that to be abused by New Zealand flying in and moving around the countryside ignoring local sensitivities." Hoadley says the New Zealand government faces pressure from many corners when citizens are caught in conflict zones and it often has scant information about an operation because things are changing by the hour. "About half of New Zealanders never bother to register in a foreign country and of course they're vulnerable, more at risk because MFAT cannot contact them, their families cannot contact them often and then the families will ring up the Minister of Foreign Affairs desperate to contact their son, daughter, brother, sister in a war zone and this puts a lot of pressure on the minister, the ministry, the bureaucrats and others." Jerusalem-based Samoan Vincent Schmidt tells The Detail how he used his contacts as a security officer for the United Nations to get a young Samoan student to safety after she was stranded in Israel last week. But it took several days and involved the Samoan ambassador in Belgium and the government back in Apia to get Polino Falevaai home. Schmidt explains how they all communicated by WhatsApp, as Falevaai travelled by bus for four to five hours over the border into Egypt, encountering a number of checkpoints before she faced a two-day wait in a chaotic Cairo airport. "There were a couple of flights that got cancelled a couple of minutes before she had to board the plan but because of the checkpoints they got delayed, there was a miscommunication with the school. Yeah, there were a lot of challenges," says Schmidt ReliefAid humanitarian agency founder Mike Seawright recalls a high risk situation in Syria under the brutal Assad regime when he had to evacuate 100 workers at a hospital close to the front line. They had to flee in minutes but one doctor refused to go. "I'm saying to the guy, 'you don't get an option here, you are relocating no matter what you think. Get on that truck, you're putting other lives at risk here, we'll come back as soon as we can but at this point we don't know if hell on earth is going to open up around this clinic, this hospital'," says Seawright. Until recently he says, it was impossible to get insurance for his workers in hotspots such as Ukraine, Gaza and Afghanistan, making the delivery of aid and the care of his team even more costly. That added to the complications of managing teams of workers that were both local and international. Seawright says Gaza is by far the riskiest location right now. "When we started in Gaza we started with a team of nine in the north ... of the nine, seven are now dead, and two are severely injured. Even our team in Ukraine and our team in Syria ... they tell us to be careful in Gaza. Even places like Ukraine which in itself is extremely dangerous." Security expert James Robertson of International SOS says working with clients in the Middle East has been "intense". One of the challenging parts is pulling together a disparate group of people and preparing them for a difficult border crossing. "When you're trying to co-ordinate lots of different clients, each of whom has a different risk tolerance, a different appetite for uncertainty and friction, I suppose, trying to co-ordinate them together to make a response on the ground can be pretty tricky."

In a groundbreaking development, Chinese scientists have unveiled a novel method for extracting ultra-pure rubidium chloride from brine containing trace amounts of the metal. This achievement is a significant milestone for China's critical minerals supply, potentially reducing the country's dependency on foreign imports. As the world's largest consumer of rubidium, China has been reliant on countries like Canada for the majority of its imports. The breakthrough, reported by the Qinghai Institute of Salt Lakes, showcases China's growing expertise in strategic mineral extraction, promising a more self-sufficient future in high-tech and defense applications. The Significance of 99.9% Pure Rubidium The Qinghai Institute of Salt Lakes (ISL), a division of the Chinese Academy of Sciences, announced this remarkable achievement. Researchers succeeded in producing rubidium chloride with an astounding 99.9% purity from potassium chloride material, which contained a mere 0.001% rubidium. Previously, this ultra-low concentration was deemed commercially unviable, but the new process has changed that perception entirely. Rubidium is a soft alkali metal with critical applications across multiple sectors. It plays a vital role in high-tech fields, including atomic clocks, perovskite solar cells, aerospace systems, and specialized glass. The importance of rubidium is underscored by its use in ultra-precise atomic clocks, which lose less than one second over 3.7 million years. Additionally, its applications extend to medical research, particularly in imaging tumor cells. Despite holding some of the world's largest rubidium reserves, China has faced challenges in domestic development, primarily because over 97% of its rubidium is locked in low-grade hard rock deposits that are difficult and costly to process. Only a small fraction of rubidium is found in more accessible forms, such as salt lake brine, predominantly in Qinghai province and Tibet. This breakthrough could mark a turning point in China's rubidium industry. 'Biggest Wind Turbine Ever': China Smashes All Records With This Colossal Machine—But a Hidden Flaw Threatens the Whole Project A First for China: Reducing Dependency In 2021, China imported over 19,500 tons of rubidium concentrate, with a dependency rate of 66.3% on external sources like Canada and Zimbabwe. The addition of rubidium to the United States' critical minerals list in 2022 heightened the geopolitical stakes surrounding mineral access. He Xinyu, in China Mining Magazine, emphasized the need for China to bolster resource security through technological innovation and diplomatic engagement. The ISL's electrochemical separation group addressed the scientific and engineering challenges of rubidium extraction. They developed a high-fidelity model to trace rubidium's distribution during potassium salt processing, identifying the reasons for rubidium's resistance to enrichment. This model not only optimizes rubidium concentration but also has potential applications in resource mapping and separation techniques. The integrated process devised by ISL encompasses ore washing, rubidium leaching, enrichment, solvent extraction, and purification. This system has been successfully tested using potassium chloride from Qinghai's Qarhan Salt Lake, one of China's largest inland salt lakes, consistently yielding 99.9% pure rubidium chloride from low-grade feedstock, which was previously considered unusable. 'China Leaves West in the Dust': Its Small Nuclear Reactor Leap Puts Beijing Years Ahead in the Future of Clean Energy Impact on Costs and Industrial Resilience Beyond its technological significance, this innovative process could result in substantial cost savings. A 2022 cost analysis by ISL scientist Gao Dandan's team found that rubidium chloride produced through this method could be manufactured at just one-third of its current market price. This economic advantage could strengthen China's industrial resilience amid growing global competition for strategic minerals. Supported by the National Natural Science Foundation, CAS, and Qinghai provincial authorities, this development signifies a crucial step in China's pursuit of self-reliance in strategic mineral resources. By enhancing its capacity to produce rubidium internally, China is better positioned to withstand external pressures and maintain its lead in high-tech sectors. This breakthrough not only underlines China's commitment to technological advancement but also its determination to secure essential resources. As the global demand for strategic minerals intensifies, China's innovative approach could set a precedent for other nations seeking to bolster their mineral independence.
